How to look after your hot tub

My New Hot Tub Has Arrived – What do I do now?

Hot tub commissioning with All SwimAssuming you purchased your new hot tub from a reputable supplier, you will have benefitted from having it properly installed and commissioned as part of the delivery service. A part of that service likely included having the hot tub filled with water and treated with chemicals, and a demonstration of how to use the control panel to operate the tub properly.

Great as that is, many new hot tub owners find it a little tricky at the beginning to maintain proper water balance and in the day to day operation and maintenance of the tub - in fact we always tell our customers we expect to be on hand to answer any questions or concerns in the post-delivery first few weeks!

Getting To Know Your New Hot Tub

As with any new item, it always pays to spend some time at the start familiarising yourself with the operating instructions. That way, you can enjoy using your tub as and when you want to – minus the headache of frantically scanning the user manual trying to figure something out at the last minute, when you’re expecting guests (haven’t we all been there at some point?!)

Some of the common queries we receive from new tub owners include:

Why Is My Hot Tub Not Heating Up?

The first thing to double check if you encounter a problem with your hot tub not heating up is the operating mode the tub is set on. Hot Tubs typically have three modes; Standard, Economy and Sleep (or Ready and Rest depending on the manufacturer). Here’s a brief explanation of what each mode means:

Standard: In standard mode the set temperature will be reached and consistently maintained.

Economy: In this mode the heater will only come on when the tub is in one of its standard filter cycles (typically for 1.5-2 hours twice a day, morning and evening) if the temperature is below the set temperature. Economy is ideal for daily users.

Sleep: Working on the same principle as Economy mode, but in Sleep mode the drop in temperature usually has to be 10 degrees below the set temperature for the heater to kick in during the filter cycle. Sleep mode is most commonly used when going on holiday or periods of absence where nobody will be using the tub.

I’m Struggling To Maintain Correct Water Chemistry

The most common query we receive by far from new hot tub owners is due to cloudy or murky water along with how much of each chemical they should be adding and when. And it’s no surprise, as there is a lot to get to grips with, particularly if you have never owned a hot tub before! High usage and being unfamiliar with water testing and chemical dosing are the usual causes of incorrect water chemistry during the first few weeks.

Some tips we offer are to get in the habit of regularly testing the water using the testing strips in your chemical starter pack. This will help you to understand when the water is calling for higher levels of sanitiser or pH adjusters etc, and it’s a habit that will save you stress and money over time.

Did you know that the ideal time to add sanitiser is after use, not before? This way, the sanitiser gets to work straight away on cleansing and cleaning the water – whereas if left until the following day, bacteria has had a whale of a time already starting to multiply overnight – beat it at its’ own game!

Factors that will increase the need for sanitiser are users not showering prior to use or removing make up (fake tan loves to make a filter cartridge work hard too). So, it’s a good habit to adopt from the start asking bathers to rinse off before using the tub – you could even get a little sign printed if you don’t like asking, or forget to ask.

Keeping a close eye on your pH level is important too, as if the water becomes too acidic or alkaline it can make for an uncomfortable user experience, and take its toll on the hot tub equipment.

What Do I Need To Do With Spa Frogs?

Spa Frog bromine and mineral cartridges Our range of Caldera Spas have in-built water care courtesy of a Bromine Spa Frog cartridge and Mineral Frog cartridge. One is prefilled with Bromine to sanitise the water, reducing the need for sanitiser top-up dosing by up to 50% and the other with minerals, which condition the water for a softer feel.

You control how quickly these are administered into the water via a simple dial on the cartridges, allowing you to increase or decrease the level as needed (ideal for a weekend away, simply turn up the dial for automatic Bromine sanitisation!)

Frequency of changing Spa Frog cartridges depends on how you set the dials, and changing the cartridges is straight forward; ensure all jet pumps are turned off before opening the cap of the in-built housing compartment. Turn the handle counter-clockwise and lift the holder up and out before setting the dial on the new cartridges and inserting them into the holder. Secure them back into place by pushing the compartment down and twisting it clockwise, then close the cap.

How Often Should I Change The Water?

BISHTA guidelines recommend changing the water in your hot tub at least every 3 months, more frequently in the case of high usage.  This will help to ensure optimum water quality and protect both bathers and the hot tub equipment.

Top Tip; Prior to emptying your tub, it is recommended to use a ‘flush’ such as Hot Tub Flush to thoroughly clean all of the internal pipework, removing debris and any bacteria lurking within.

Changing Filter Cartridges

As a guide, your filter cartridges should be removed and cleaned every 2 weeks or so, depending on usage. This can be done either by soaking them overnight in a cleaning solution like our Blue Horizons filter and cartridge cleaner or by using an instant solution eliminating the need to soak like the All Swim instant filter cleaner following the usage instructions on the label. New cartridges should be replaced approximately every 6 months.

Cleaning The Hot Tub

Hot tub commissioning with All SwimRegularly cleaning the surface of your hot tub will help keep the exterior in tip-top shape and help minimise scratching or marking the acrylic shell, while keeping it looking great. Surface cleaners such as our Lo-Chlor Spa Shield are great for polishing up the surface of the shell, simply combine with a soft microfibre cloth to buff the shell, taking care not to get the product in the water. When changing the water, take advantage of that time to give the entire shell a clean before you refill with fresh water to keep it looking good as new (just ensure there is no residual product on the surface before refilling.)

You’ve Got It Sussed!

Hopefully the above tips will prove useful when it comes to taking care of your hot tub and you can also find more information on our Frequently Asked Questions page that may be of interest. For any queries or areas of concern, if in doubt, check it out with your supplier or give us a call on 02920 705059 for further help and advice.

What you get for your money when buying hot tubs

How much should a Hot Tub cost?

Caldera Spas Utopia Series hot tubs The simple answer to that question is, it depends on the hot tub! If you’re completely new to hot tubs you may be considering an inflatable spa for around £500. With a small initial outlay these hot tubs are a great way to see if you and your family are suited to a hot tub lifestyle. Upgrading from this price point you may be considering a rota-moulded hot tub that typically start from around £3,500 and, at the other end of the spectrum, are the very best portable hot tubs commercially available that can exceed £15,000. The reason for the differences in prices is down to size, features, manufacturing materials, design, the performance that the hot tub delivers and the type of manufacturer’s warranty offered.

Perhaps a more important consideration is what you actually value in a hot tub. When you’re spending time relaxing in your hot tub do you want to be worrying about how expensive it is to run or how well insulated that cabinet really is for the money you paid? Do the quality of the hydrotherapy jets matter to you and that troublesome lower back pain you’ve been suffering with? Or maybe including multicoloured lighting and a waterfall in the price will really make a difference to your planned entertainment needs? Well, to help you make the very best decision when considering a new hot tub here’s our guide to the key features you’ll find on a hot tub and how they can affect the price.

How size affects your hot tub price

Generally speaking the larger the hot tub you are considering, the higher the price is likely to be. This comes down to the fact that more materials are going to be needed to build a larger spa along with a need for more jets, larger, more powerful pumps and even filters with increased filtration capacity. All of these factors determine cost and don’t forget, with bigger footprints, larger spas require more storage space during transportation, again adding to their overall price. Before buying a new hot tub carefully consider how it will be used and by who, you may be a couple without children or in retirement and are looking for some personal therapeutic use, in that case our Caldera Spa Aventine, Celio and Kauai could be the perfect fit for you. Alternatively, you could have a large family or may be a bit of a sociable butterfly entertaining a wide circle of friends. In that case our Caldera Spas Vanto, Salina or Cantabria could be the perfect choice for you with seating for 7-8 people you really are spoilt for space and comfort!

Does adding features add cost?

Caldera Spas Cantabria EcstaseatHot tubs have evolved quite considerably over the last decade and, it’s safe to say, so have our expectations! We expect a lot more from our commodities these days, smart phones now deliver our favourite films and shows on the go, we can transfer money via our tablet devices and browse the internet on our TVs and hot tubs are no exception. We all expect an incredible spa experience and most hot tubs offer a certain level of this. If you are looking to spend more money on a hot tub then you can expect more advanced, diverse hydrotherapy jets, more powerful and silent running pumps together with more intuitive control from your spas display panels and more sophisticated water care systems that help you reduce the need for hot tub chemicals. State of the art music systems, bass hungry sub woofers, multi colour change lighting and waterfalls will also add to the overall experience when using your spa, together with that overall cost.

So before you consider a purchase decide what will matter most to your spa experience. If you’re looking for a peaceful retreat from a hectic working life then the quality and variety of powerful hydrotherapy jets could be the most important consideration for you. If so, make sure you discover the Atlas Neck Massage on our Utopia series of Caldera Spas and in particular the incredible UltraMassage lounge seat on the Cantabria featuring the customisable UltraMasseuse System, the absolute pinnacle of hydrotherapy massage relief! Alternatively you may be looking to use your hot tub as an entertainment piece, so perhaps a sound system incorporating individual seat speakers and easy to use, intuitive bluetooth technology is going to be your first priority. We’re all different and will use a hot tub in our own unique ways but thankfully, with so much product diversity and unique features, our Caldera Spas offer something for everyone.

Is hot tub design really a consideration for me?

Euphoria footwell jets on the Caldera Spas Tahitian hot tubThis element is often overlooked and least considered by customers when buying a hot tub. Good design will often go un-noticed because you’ll find using a well designed, well considered hot tub effortless. Badly designed lounger seats and poorly positioned jets can cause you to float out of position when using your hot tub and having to constantly adjust yourself can create unnecessary body tension, somewhat counter productive to a hot tub delivering relaxation and stress relief! Make sure you look at the ergonomic seat design and wall structure of any potential hot tub as well, curves are more comfortable than straight sides and great design always maximises the occupant space when in use.

Other little features that make a big difference are the positions of the control panels (within arms reach is ideal) and the size of the footwell space. Regardless of how many bums on seats a manufacturer may quote on it’s glossy literature take a close look at the all important footwell space. Hot tub’s designed with a generous amount of legroom and footwell space will give you, your family and friends a much more comfortable experience when using the hot tub.

A good hot tub will offer much more than just a centre piece for your garden, it should become part of your lifestyle and fit every aspect of your daily routine perfectly. Pay close attention to the inviting colours, cabinet textures, seat and lounger shapes and interior and exterior lighting of our Caldera Spas, you’ll probably agree that they offer that little bit more.

What you should consider with performance

Caldera Spas Vacanza Series Vanto hot tub coverProbably the most difficult aspect of a hot tub purchase is considering the performance that it’s going to deliver on a day to day basis. Although many hot tubs may look similar there are many differences between low and high end spas. Although cheap hot tubs may have many jets, there could be cost savings being made underneath the cabinet with underpowered pumps providing a less intense, less satisfying hydrotherapy experience. The best hot tubs on the market are fitted with powerful, yet quiet, circulation pumps that are able to efficiently circulate the water through the hot tub filter and heater with ease.

Superior performance can also be measured in the efficiency of the cabinet insulation to help keep heat in the spa water. All Caldera Spas feature a revolutionary FibreCor technology that is four times more efficient than traditional foam insulation used on cheaper hot tubs. Perhaps the last consideration on any one’s mind when looking at a new hot tub is the base pan design. Base pan what? This is the part of the hot tub you may only see on the day of installation (when it’s delivered on it’s side) but it is always in contact with the ground, another area for heat loss. Our Utopia range features a new ABS base pan that has a corrugated design to help minimise contact with the ground and protect the components, improve energy efficiency and add support.

So ask yourself, if Caldera Spas go to so much trouble to make the parts you don’t see as well designed and efficient as possible in terms of performance, how much time do they invest in the components you do see on their hot tubs? And, perhaps more importantly, are cheaper hot tubs from other manufacturers going to deliver you the same performance.

So what next?

This guide should help you make more considered, informed buying choices when you’re buying a new hot tub and should give you a better idea of what is actually being offered at the price point you consider.

At All Swim we always recommend looking at a prospective purchase rather than just ‘buying online’ as you have the opportunity to closely examine your new hot tub and really get a feel for the quality of the build. We also offer wet tests at our hot tub showroom here in Cardiff so if you really want to discover the Caldera Spas difference we would be more than happy to see you!

Choosing the right massage table for you

Providing effective sports, beauty and medical therapy starts with the right massage table

Affinity Portable Flexible Massage tableWhether you’re a student, a newly qualified therapist or have been treating clients for years, without doubt, one of the most important factors in your ability to work well is finding the right Massage Table. In today’s fast-moving marketplace there are many different styles and qualities of massage table available, so how do you find the right one for you, your clients and the specific treatments you offer?

What To Look For In A Massage Table

The list is long; is a flat massage table adequate or do you need it to have a lifting backrest? Weight will be a key factor if you need a portable couch and which support structure is more suitable – wood or aluminium? It’s a competitive arena for therapists, and a crucial part of gaining your clients repeat custom lies in the creation of a comfortable, relaxing environment - ( starting with the treatment bed they’ll be lying on.

It can be a confusing minefield, best avoided by considering the following criteria prior to making your all important decision:

  • Which massage table has adequate strength and stability for the treatments you offer? If you perform vigorous types of treatments such as sports massage or physiotherapy, you’ll need a table strong enough to go the distance on a regular basis.
  • How flexible is the massage couch? Reiki practitioners for example will find Reiki end panels and the ability to tilt the bed on an angle essential.
  • Height is another important factor – be sure to check the adjustable height range is suitable for your treatment range (Will you need to sit at certain points? Do some of your clients have difficulty getting onto a high couch? If so your table will need to be at a low level on occasion. A higher level table may be more suitable if you stand throughout treatments.
  • What is the foam thickness and composition? Beauty treatment clients tend to appreciate a more luxurious padding, aiding relaxation during their session – plus it gives a more high-end appeal to your brand image. Consider also if a face cradle or breathe hole is better, and if an arm rest would enhance your treatments.
  • Affinity Sports Motorised Massage tableDo you need a narrow or wide massage table width? Therapists of 5’4” or under will find a table width of 29” or under best, whereas if you are 5’10” or over you should opt for a table width of between 27” and 33”. Similarly, those with larger clients on a regular basis will find a wider table width useful, whereas a narrower table is ideal for getting in close and delivering pressure massage and stretching (plus it will be easier to transport around of course!)
  • Are you mobile or at a fixed location? A table no heavier than 15kg is ideal for mobile therapists, plus the ease of set up and put down of your massage table could add up to a lot of time savings.

Not All Massage Beds Are Created Equal

With such a wealth of choice and wide range of prices available in the world of massage tables, it can be tough identifying the right one for you, especially if you’re starting out and have a limited budget available.

In the same way your clients put their trust in you to provide them with a high quality treatment session, you need to be sure you are equipped with a trustworthy massage table that is strong, comfortable and hard-wearing enough to sustain regular usage.

Understanding water balance in your swimming pool and hot tub


All Swim stabilisedchlorine granulesWhen chlorine is added to pool or spa water a portion is consumed in the process when it destroys bacteria, algae and other contaminants introduced to the swimming pool or hot tub water. The amount of chlorine consumed is known as chlorine demand. Sunlight, bacteria, perspiration, urine, algae, make up, fake tan and many other forms of debris all create this chlorine demand.

Once this initial demand has been met, the chlorine that remains in the water is referred to as the total residual chlorine, which is a combination of free available chlorine and combined chlorine. The free available chlorine is the active chlorine that’s left to kill any new contaminants entering the pool or spa. Combined chlorine is tied up in nitrogen and ammonia compounds referred to as chloramines, which remain in the water from organic waste from swimmers and bathers. Chloramines are responsible for eye irritation and the chlorine odor that some people find offensive. When chlorine is tied up in chloramines it loses most of it’s effectiveness as a sanitiser.

To keep a swimming pool or hot tub sanitary with chlorine it is necessary to maintain the following free chlorine residuals:

  • Residential Pools between 1.0 and 3.0ppm
  • Commercial Pools between 1.5 and 2.0ppm using Calcium Hypochlorite or Liquid Chlorine, sometimes a little lower if using UV
  • Residential & Commercial Hot tubs and Spas between 3.0 and 5.0ppm

When levels are kept within this range chlorine is able to control organisms as well as destroying any new contaminants entering the pool or hot tub.

Super Chlorination

Super chlorination is recommended as a weekly treatment if temperatures exceed 90 degrees, when your swimming pool or spa is receiving a heavy bather or swimmer load, is subject to long periods of rain or when high winds carry debris and pollen into your pool. Super chlorination is the addition of an extra dose of chlorine to pool or spa water, which brings the free available chlorine levels to 3.0 to 5.0ppm (Generally a super chlorination boosts the free chlorine level up to between 5 – 10ppm). This helps restore the chlorine’s ability to control algae and bacteria. Some algae spores can also become immune to small doses of sanitisers so super chlorination can help combat this.

Shock Treatment

All Swim stabilisedchlorine granules Shock treatment is a larger dose of chlorine to bring the free available chlorine level up to 10ppm. This is intended to control visible algae, burn out organic swimmer and bather waste and destroy excess chloramines. When swimmers complain of burning eyes and a strong chlorine smell, it is due to excess chloramines and not enough free available chlorine residual in the water - not too much! The odour can also be even stronger if the pH is also low. The use of a periodic shock treatment along with a normal chlorination routine will aid in the prevention of undesirable side effects of using your swimming pool or hot tub. After shock treatment do not resume swimming or bathing until the chlorine residual drops to below 3ppm.

Please note, if your chlorine reading is very high, typically 10ppm, you may obtain a false result when testing for pH with a testing kit. In these cases lower the chlorine levels first before testing for pH and total alkalinity.


Bromine is another type of pool and hot tub sanitiser, although it is quite different to chlorine. If you using Bromine you won’t require a conditioner (an additive that helps prevent chemicals dissipating under the action of the ultraviolet rays of the sun). Like chlorine, bromine combines with nitrogen and ammonia compounds to form bromamines (as opposed to chloramines). Unlike chloramines, bromamines do not irritate eyes or have an offensive odour, and bromamines are effective sanitisers. Bromine is a more effective sanitiser at higher temperatures and therefore is a popular choice for hot tubs and with pool and spa users that dislike the unpleasant odour associated with chloramines.

A molecule of bromine is 2.25 times as heavy as chlorine, a 1.0ppm chlorine residual is therefore equivalent to a 2.25ppm bromine residual. Therefore, it is important to maintain the following bromine levels:

  • Residential & Commercial Pools between 2.0 and 4.0ppm
  • Residential Hot tubs and Spas between 3.0 and 5.0ppm
  • Commercial Hot tubs and Spas between 4.0 and 6.0ppm

When levels are kept within this range bromine is able to control organisms as well as destroying any new contaminants entering the pool and hot tub.

PH & Total Alkalinity

The two most important factors in controlling your sanitisers ability to kill bacteria are pH and total alkalinity levels.

All Swim PAK 2pH is a value expressing the relative acidity or alkalinity of swimming pool or hot tub water. It is expressed as a number from 0 to 14 with 0 being the most acidic and 14 being the most alkaline. A value of 7.0 is neutral. Low pH values cause corrosion of equipment and pool or spa surfaces. High pH values cause scale to form on equipment and on pool or hot tub surfaces. The ideal range for pools is 7.2 - 7.6 and the ideal range for hot tubs is 7.0 - 7.6. For swimming pools, to raise pH you will need to use Sodium Carbonate or PAK 2 and to lower pH you will need to use Sodium Bisulphate or Pool Acid. For hot tubs, to raise pH you will need to use Aquasparkle pH Plus and to lower pH you will need to use Aquasparkle pH Minus.  

Total Alkalinity is the ability of water to resist a change in pH. It is also commonly known as the buffering capacity of water. High alkalinity makes it hard to change the pH and may cause scale. Low alkalinity causes dramatic changes in pH, often referred to as pH bounce, and causes corrosion of equipment and pool or hot tub surfaces. The ideal total alkalinity varies depending on the type of sanitiser you are using. For swimming pools, to adjust your Total Alkalinity you will need to use Bicarbonate of Soda or PAK 1. For hot tubs you will need to use Aquasparkle TA Plus.

Always remember, total alkalinity is the key to water balance. Always adjust total alkalinity first and then adjust the pH.

Sanitiser type Ideal Total Alkalinity range

Liquid Chlorine
Calcium Hypochlorite

80 - 100ppm

Gas Chlorine
Trichlor tablets
Bromine tablets

120 - 140ppm

Dichlor granules
Two part bromine

100 - 120ppm

pH and Total Alkalinity are related. It is not possible to change one without affecting the other.

Conditioner or Stabiliser

Whatever type of chlorine chemical you use in your swimming pool or hot tub as a disinfectant is a very active chemical that is easily dissipated by the ultraviolet rays of the sun. To prolong the useful life of free, available chlorine the addition of cyanuric acid (conditioner) is recommended when filling a new pool or at the start of each swimming season if required. Conditioner acts as a type of chemical umbrella, protecting the chlorine sanitiser against loss against the sun’s UV rays. The ideal range for pool stabiliser is 30 - 50ppm. All Swim Conditioner is ideal for adjusting the levels of stabiliser in your swimming pool.

Calcium Hardness

All Swim PAK 2Calcium hardness refers to the portion of the swimming pool or hot tub water’s total hardness due to calcium salts. Calcium hardness will vary with your local water source, the chemicals you add to the water and the rate of evaporation. If you’re based in Wales you can check your local authority’s source water quality at the Welsh Water website.

High calcium hardness can cause cloudy water and also cause the formation of scale on pool and spa equipment. If hardness reaches a level of 400ppm, approximately 25% of the pool or spa water it should be drained and refilled. Soft water without hardness is undesirable because it can cause equipment corrosion and adversely affect the grout on concrete tiled pools. Recommended hardness levels are 200-400ppm for tiled pools and 175-250ppm for vinyl, fibreglass or other types of pool and spa surfaces. Increasing water hardness can be achieved with the use of All Swim’s Pak 3, Calcium Chloride.

Phosphates and their relationship to algae in green pools

Win The War Against Algae This Season

Green swimming pool caused by algae formationWithout doubt, one of the most irritating things for swimming pool owners is the dreaded appearance of algae in your pool. Not being able to use the pool during the algae elimination process, the expense of treating the problem and so on.

It is a common problem amongst pool owners, and for many, when the algae is caught early and swift action taken to tackle it they find it easy enough to manage.

However, others may find despite that knowing how to clear the pool of algae and following the correct procedure, they are plagued by stubborn recurrences of algae – and are fed up of it!

If that sounds familiar, you may be experiencing an issue with the level of Phosphates in your swimming pool. Phos-what?! Allow us to explain…

What Are Phosphates?

Phosphates are pollutants that also happen to be a form of plant-food. They are present in rainwater, fertilizers for landscapes, soil and leaves – all of which can find their way into your swimming pool water. When the level of phosphates in water builds up over time, it provides an excellent food source for algae, which alongside light, water and carbon dioxide set the perfect conditions for algae to thrive in.

Green swimming pool caused by algae formationWhat Can Be Done To Stop Recurring Algae?

As mentioned above, algae requires four components to enable it to thrive; Light, Water, Carbon Dioxide and Food. By removing one or more of these components, algae will struggle and be unable to thrive. If you find that algae keeps making an unwelcome return to your swimming pool each year, you more than likely have a higher than desired level of phosphates present.

Testing For Phosphates

If all of this sounds familiar, it makes sense to test your water for phosphates. This can easily be done with the Lo-Chlor Phosphate Test Kit. Once you’ve identified a high phosphate problem, you can take the necessary steps to remove the phosphate (food) source, dramatically reducing the chance of persistent algae recurrence.

How Do You Remove Phosphates?

Lo-Chlor Starver XWhen conducting a shock treatment to kill off algae you typically conclude the treatment process with either a clarifier or floculant product to remove the dead algae spores from the pool water.  While this appears to resolve the problem, phosphate particles are very small and do not get removed at the same time. They remain in the water, waiting for the next batch of algae to emerge!

Fear not though, as there are products specifically designed to remove phosphates; Lo Chlor Starver Phosphate Remover and Lo-Chlor Starver X. These products are a natural composition of unique polymers and rare earth compounds, proven to safely and effectively remove phosphates from swimming pool water, ponds and fountains.

Both Starver and Starver X are fast acting while simultaneously increasing the efficiency of sanitisers and salt water chlorinators. There is no need to vacuum to waste as no residue settles in the pool and they are compatible with all pool treatment products and equipment.

We offer free, comprehensive advice on all manner of water chemistry queries and managing your swimming pool too of course, so please feel free to get in touch with any questions you have either by calling 02920 705059, emailing or visiting our swimming pool and hot tub showroom here in Cardiff.

Heatsavr and Ecosavr, the liquid swimming pool cover

What is a liquid pool cover?

Heatsavr is an effective ‘liquid pool blanket’ for swimming pools and spas that replaces the need for conventional pool covers, greatly reducing heat loss and evaporation from exposed pool surfaces 24 hours a day.

Heatsavr is a patented, non-toxic, biodegradable and completely safe liquid that does not change the appearance or operation of your pool and has been fully tested by numerous independent authorities to ensure that it meets the health and safety standards required.

What are the benefits of Heatsavr over conventional pool covers?

  • Low capital cost
  • Quick payback – costs funded directly from savings
  • Available 24/7
  • No cleaning issues due to bacterial build up
  • Fully automatic – no cover to remove
  • Pool always ready to use
  • Ultimate reliability
  • Energy Savings up to 50%

Using Heatsavr for outdoor pools

An outdoor swimming pool before using Heatsavr Heatsavr works like conventional solar covers for outdoor pools by enabling the pool to benefit from direct solar radiation, so an unheated pool will be naturally warmer or a heated pool cost less to run. Savings relate directly to reduced evaporation and hence pool water heat loss. Heat savings of up to 40% can be expected using Heatsavr although actual savings will depend on location and usage.

Using Heatsavr for indoor swimming pools

In addition to savings on water heating, Heatsavr also reduces the overall energy usage which includes dehumidification and air heating. Reduced evaporation means less load on any dehumidification plant and when the pool is unoccupied the air temperature can be reduced to a set back level, resulting in reduced air heating costs. Dependant on building design and pool usage, overall reduction in energy costs can be as high as 50% when using Heatsavr compared to an uncovered pool.

Chemical Savings of up to 50%

An outdoor swimming pool after using Heatsavr liquid pool cover Whilst the chemical saving benefits of Heatsavr have long been recognised, controlled tests carried out on several outdoor pools during 2011 showed reductions in chlorine consumption of between 45 and 50% - economic justification alone for the use of Heatsavr without taking into account the energy savings!

How does Heatsavr work?

In non-technical terms Heatsavr is a mixture of carefully chosen ingredients which are lighter than water so the mixture automatically floats to the surface. The particles of the liquid are then attracted to each other so they always try to form a perfect, very thin layer - one molecule thick - over the whole surface of the pool. They are individually so small that they are 500 times smaller than the spaces in a super high quality filter so you won’t lose performance from your swimming pool filtration system.

Unlike a conventional pool cover which has to be removed from the pool for swimming, the Heatsavr molecules break apart locally whenever the water is sufficiently disturbed but when the water calms down again they regroup to re-form the protective layer.

Easy and inexpensive to install, it provides a reliable and accurate method of ensuring that the pool benefits from the maximum energy savings possible. Fully programmable to suit pool size and hours of operation, it only requires a periodic check of the reservoir, topping up as necessary.

How to calculate the application rate of Heatsavr

Calculate your swimming pool’s surface area (length x width) then add 0.8ml per sq metre every 24 hours for a skimmer pool and 1ml per sq metre every 24 hours for a deck level pool. To help automatically dose you can use a Heatsavr dosing pump to ensure the Heatsavr liquid is added to your pool on a regular basis.

  • Save money, water & energy
  • Biodegradable: Environmentally friendly
  • Reduces make up water
  • Proven: Lab & field tested and verified
  • Easy to use – no manual handling
  • Reduces humidity in indoor pools
  • An outdoor swimming pool before using HeatsavrSafe: Tested extensively
  • Transparent
  • Safe for filters & plumbing

Heatsavr is also undetectable by pool users as it’s  tasteless, odourless and leaves no residue on your hair or clothing.


For a handy way to dose your domestic swimming pool with Heatsavr why not try the Ecosavr Fish? Combining the effective ‘liquid pool blanket’ treatment in a handy, easy to use sachet. One Ecosavr Fish treats a pool up to 40m2 for approximately one month, larger pools will require two Ecosavr Fish.

A proven alternative to hot tub chlorine and bromine

AquaFinesse: The Alternative Sanitiser

Aquafinesse Spa Kit, the alternative to chlorine and bromine sanitisers for your hot tubAs a hot tub owner, one of the first things you come to understand is the importance of sanitising the water in your spa, right? A vital step in looking after both the health and wellbeing of those using your hot tub and the water quality involves eliminating and killing bacteria, protecting users from the unwelcome, hazardous effects bacteria can pose.

An Alternative Choice

Whilst the majority of hot tub and spa owners still tend to use either Chlorine or Bromine as their sanitiser of choice, did you know there is an alternative product that not only destroys bacteria, but actually prevents it from reforming?!

The AquaFinesse Effect

Firstly, let’s ensure we fully understand the cause of bacterial build up; in order for it to thrive, bacteria creates a layer of slime where they feed, shelter and breed (gross isn’t it?!). As time passes, the slime (called Biofilm) actually increases in thickness, becoming increasingly resistant to sanitisers. In fact, 99% of all bacteria actually live in the Biofilm, only 1% of bacteria present in a spa lives in the water itself!

This then lurks invisibly on surfaces in your hot tub and within the pipework – and even high levels of chlorine or bromine are only able to kill off bacteria in the outer layer, with the remaining bacteria still present (and able to continue breeding) underneath.

Aquafinesse Spa Clean, for deep cleaning your hot tubAquaFinesse is a simple, environmentally friendly, patented weekly treatment that really takes bacteria and biofilm to task; this unique formula acts by loosening the slimy layer of biofilm from surfaces and pipework, which the action of the water then rinses away. Bacteria is also prevented from reforming, as it simply can no longer stick to surfaces during the presence of AquaFinesse. Only a very small amount of sanitiser is required alongside AquaFinesse. An added bonus is AquaFinesse’s ability to prevent calcium build up (your hot tub will thank you for this!).

How Do I Switch To AquaFinesse?

If you have previously been using chlorine or bromine as your sanitiser, you will need to perform a ‘deep clean’ with AquaFinesse Spa Clean prior to changing over AND to shock dose with your sanitiser at the same time. This action kills off and releases the bacteria present. Next you will need to drain your hot tub and fill with fresh water.

Then you can simply continue to use AquaFinesse weekly and enjoy crystal clear, softer and safer spa water every use.

Finding your perfect swimspa fit

Are swimspas going to be big enough to swim in?

Endless Pools E2000 Fitness System swimspa swimming and hot tub This is a question we get asked regularly from customers looking at purchasing swimspas, and the answer is yes, of course. You don’t need a large area or a deep body of water to be able to swim effectively. If you’ve ever used public swimming pools you probably didn’t need to adjust your swimming stroke when transitioning from the deep end to the shallow end, and the shallow end of a municipal pool will usually measure 0.9 metres in depth (some of the swimspas in our range are deeper than this).

So what is a swimspa and how does it work?

Well, a swimspa is a product that allows you to swim continuously against a current without having to turn or change direction. Whether you're a fitness fanatic training to keep fit and healthy, or looking to endure the extreme demands of competitive swimming, open water swimming, triathlons or iron man competitions, a swimspa can provide you with a tailored, adjustable swim current strength to suit your individual fitness needs. They also have their own integrated heaters so you can adjust the water temperature to suit you. They're a bit like an oversized swimming hot tub!

Swimspas work by either using a system of jets to create an adjustable water current to swim against or, in the case of our Endless Pools Fitness Systems, use the unrivalled Endless Pools Swim Machine to provide the water current for you. Either system will work well to help you increase your swimming fitness and choice is usually dependent on your needs and proposed use.

Which swim current will be the best for me?

This will depend entirely on your individual needs and how you will be using the swimspa. You will either be considering a jetted swim lane or a swim current system. Don’t worry, our trained sales staff are here to help you make the right choice for you but we can let you know a little bit about each type of system to help you understand how to make the right choice for you. We also have the X500 Swimcross Exercise System and E2000 Endless Pools Fitness System available to view and wet test at our Cardiff showroom, just bring your swimming costume and a towel to try these fabulous swimspas for yourself!

Swim jets are designed for both swim and water workout exercising and are suitable for all ages, body sizes and skill levels. Our SwimCross Exercise Systems feature five swim jets and are driven by two pumps providing a powerful and steady water stream of 1,200 litres per minute. The SwimCross jet design is also unlike many other because they don’t rely on introducing air to the swim current to add extra force, instead they use a boost effect to draw in more water, multiplying the volume and resulting in a stronger resistance for swimming against with less turbulence. This means you will find it easier to stay centered on the swimlane and the unique lift provided by the lower jets gives you added buoyancy when in the water.

The Endless Pools Fitness Systems is a swim current system that will appeal to regular swimmers and fitness enthusiasts right through to serious competitive swimmers, triathletes and iron men and women, it offers you the ultimate in swim lane technology. The industry leading Fastlane swim machine provides a superior swim-in-place experience, is custom made and the hydraulically powered propulsion system creates a laminar current of up to 19,000 litres per minute that is wider than your body and deeper than your stroke! Featuring multiple conditioning grills help smooth and redirect the water, removing air resulting in a swim current that is completely free of turbulence. Even at full power it feels like swimming in a smooth, open water current. The swim machine flow can also be adjusted from speeds ranging from 5:33 minutes (gentle breaststroke) to 1:14 minutes per 100 metres and can be precisely adjusted for perfect pace control.

These swimspas also have some great optional extras to further enhance your swim training. Choose a swim pace display system to really start measuring your performance efforts or, if you opt for a system without an underwater treadmill, add an underwater floor mirror.

Can I choose a size of swimspa that’s right for me?

Yes you can. The SwimCross and Fitness Systems are available in a number of different sizes and depth to suit your particular needs. The respective swim lane lengths for each swimspa are then determined by the distance from the front of the swim jet to the start of the first step at the rear of the unit. This gives you an indication of the fit you will need to comfortably swim within the swim lane offered by each model.

BISHTA Approved Retailers

Why Should You Buy Hot Tubs From a BISHTA Member?

Considering the vast selection of Hot Tubs for sale on the market today it can be tough identifying the best option. You need only type ‘hot tubs for sale’ into a search engine and you’re inundated with a wealth of choice, from a huge number of suppliers – so how do you decipher the good from the too-good-to-be-true?


Hot tubs and BISHTA membersBISHTA stands for the British and Irish Spa and Hot Tub Association which was established in 2001 to ensure hot tub and spa retailers were fully trained and competent in water hygiene management and ensure their awareness of why maintaining these standards is of key importance. BISHTA consists of a world-renowned team of experts available to provide support and assistance to its registered members, ensuring promotion of high safety standards and value amongst hot tub retailers. This enables BISHTA registered members to competently advise prospective and existing spa owners on all aspects of water hygiene management and all manner of issues or questions that may arise.

Why Is Water Hygiene Important?

Whilst regular use of a hot tub will provide you with many health and wellbeing benefits it is important to maintain clean, clear and hygienically safe water in your spa to prevent unwanted, potentially harmful micro-organisms from developing.

In the case of water hygiene management, prevention is easier than the cure. The good news is that correct and safe water chemistry is easily achieved through using a combination of products including sanitisers (disinfectants), oxidisers, minerals and pH balancers, in accordance with BISHTA water treatment standards.

The Benefits of Buying From a BISHTA Member

The British and Irish Hot Tub and Spa Industry is at present not regulated by the Government or Law. This unfortunately means that neither sales of or maintenance of hot tubs is subject to a code of conduct, allowing anybody to retail or carry out maintenance on a hot tub.

Potential issues with the lack of regulation can include factors such as sub-standard quality hot tubs and parts being sold and improper advice being given regarding maintenance and water treatment which at worst can result in customers stuck with an unusable spa or water quality that poses a hazard to health.

Sounds a little doom and gloom, right? But fear not, you can rest assured when dealing with a BISHTA registered company that they have committed to honour the BISHTA Code of Ethical Conduct which includes:

  • To trade ethically with both the public and within the industry at all times
  • To comply with BISHTA’s standards for self-contained hot tubs and spas and abide by its Rules and Regulations
  • To comply at all times with the Trades Descriptions Act, 1968, Supply of Goods (Implied Terms) Act, 1973, the Sale of Goods Act, 1979
  • To ensure products and services advertised and marketed are fully understood by the prospective client and to comply with the requirements of the Advertising Standards Authority
  • To offer a clear and reasonable warranty of products and services and to perform on such warranties where justifiable claims are made within a suitable time period

The UK Pool & Spa Awards 2017

Awarding excellence in the Swimming Pool, Swimspa and Hot tub industry

Michelle Dewberry at the UK Pool and Spa Awards 2017Well, another year is fast approaching an end and it’s time for companies in the Pool and Spa industry to start reflecting on their achievements over the past twelve months and plan for the forthcoming new season. Every company hopes to build on the completion of successful swimming pool and hot tub projects year on year, improve customer service levels and make valued improvements to the overall buying experience. It’s also nice to know that those continued efforts in a business are implemented effectively and that the improvements are recognised by both customers and industry peers alike. No industry awards ceremony reflects those efforts better than the UK Pool & Spa Awards.

Now in it’s seventh year the UK Pool & Spa Awards has continued to grow bigger and better year on year and has seen an overwhelming demand for entrants with 31 award winning opportunities now on offer. The competition is open to the entire water leisure industry across multiple disciplines including swimming pool designers, swimming pool installers, hot tub and swim spa manufacturers together with retailers and wholesalers. Entering these prestigious awards is an opportunity for any company to raise their profile amongst industry leaders and customers alike.

Simply entering these awards isn’t a guarantee of success though. Each entry is judged by both a public and private vote with 40% of the overall vote being cast on-line by the general public and 60% being judged by a specially selected panel consisting of industry representatives and professionals from around the globe. If you’re going to put yourself forward for an award there aren’t many places to hide unfortunately!

As ever, we’ve continued to work hard to make improvements to the business over the last year and decided that the categories best reflecting our efforts for reward were Spa Retailer of the Year, Pool Retailer of the Year, Pool Showroom of the Year, Pool & Spa Showroom of the Year and Website of the Year. That’s 5 in total, hopefully everyone else agreed with our opinions on the improvements we had made!

So began the anxious wait for the award results at The Vox Conference Centre, Resorts World, Birmingham. As ever, the turnout was impressive with many leading industry figures present including a special guest appearance from Michelle Dewberry, a broadcaster, business woman and winner of the second series of the BBC’s, Apprentice. Our first chance to settle the nerves came with an informal networking session with major suppliers within the swimming pool, swimspa and hot tub industry followed by an introduction to the award entries and the companies looking to take home some awards. The competition was as strong as ever and winning an award was going to be an achievement this year.

Pool and Spa Showroom of the Year 2017 awardAfter a few inspirational words from Michelle on the role of technology and young women in business together with an insightful look at the pool and spa industry and the repercussions of the Brexit vote by the UK Pool & Spa Awards event organiser it was time to announce the winners. First awards category and our first entry, Website of the Year. There were some well deserved Business Award winners in this competitive field but we were stunned to be collecting our first win so early in the evening, a Gold Standard Award for the All Swim website. A great start! Next came the Commercial Pool and Project Awards with some stand out winners in the Luxury Pools and Hot Tub and Spa of the Year Awards. Finally, the Prestige Awards and the remainder of our four entries, let’s hope we followed on from our early success. Pool Showroom of the Year was announced as another Gold Standard Award for All Swim, followed by Winner of the Pool and Spa Showroom of the Year and amazingly, 2 more Gold Standard Awards for Pool Retailer of the Year and Spa Retailer of the Year. What an incredible end to an exciting evening of events, an award in every category we entered!

Jane Veysey, company director remarked:

“It’s unbelievable to receive so many awards at the UK Pool & Spa Awards this year, they are always genuinely unexpected as the competition is always very tough. I would just like to thank all of our customers for their continued support and to my team of staff who help make my business a success with their hard work and commitment.”

Here’s to another year of continued improvements at All Swim and another successful year of business in 2018, we hope you will all continue to support us as a business and enjoy the continued improvements we consistently make to our products and services.
