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, fertilisers 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 by bringing a water sample into All Swim for us to test for you. 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 flocculant 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 sales@allswimltd.com or visiting our swimming pool and hot tub showroom here in Cardiff.

Great article Matt tackling such a common problem in swimming pools. People don't realise that you can use Chlorine and algaecides to kill algae but they do not remove phosphate from the water. Phosphate levels spike after algae is killed - this phosphate is its food source being released back into the water.

You need a phosphate remover to take this out otherwise this phosphate will result in re-occurring algae. Pools that run on our phosphate removers use less chlorine, as phosphate creates a demand for chlorine. So whilst people think they are spending more money they are actually saving on their chlorine and algaecide consumption.
