One of the most common issues pool owners are facing at the moment is the pool turning green and having to then spend time and money rectifying the problem. But what causes the problem and how can you prevent it?
Algae loves the sun!
The green colour in your swimming pool is caused by the presence of algae in the water. When conditions are right, algae blooms and the pool turns green; having out of balance water, warm temperatures, sunlight and the presence of phosphates all contribute to algae growth but so does the lack of good circulation, filtration and sanitisation.
If it’s all starting to sound like a lot of hard work, fear not, it is possible to keep your pool clear and free of algae with a little commitment to the cause. It is really important to regularly monitor and test the chlorine level and to then dose the water with the appropriate amount based on the volume of water your pool holds. Another essential step during this weather is to ensure your pump is turned on and the water is circulating – not turning the pump on will stop the chemicals from circulating and allow the algae to thrive! Chlorine does a great job of sanitising the water, keeping it free from bacteria and harmful organisms. But when the weather is hot and sunny and the pool is being used a lot, the demand for chlorine increases, so you will find that your usual dose is not as effective and your water balance is suffering.
