Pure Balance Pool
The most common reason pool water turns green is due to algae growing in the water. Algae can grow rapidly, particularly in hot weather, which is why it can surprise you overnight during the warmer months. This generally comes down to an imbalance or lack of chlorine in the water.
Chlorine is an effective sanitiser; however, letting chlorine levels drop for even a day can start an algae outbreak. So, it’s important to check your chlorine levels frequently to save you any nasty surprises.
In any case, there are several simple steps you can follow to get your pool back to full health without having to drain it. Please note that these steps are for chlorine sanitiser-based pools (including salt and mineral pools).
If your pool is dark green and you can’t see the bottom, you may need to add a clarifier or flocculant the next day to remove the dead algae.
For a 50,000L green pool, you can add:
For 50,000L light-green looking pools, we recommend:
Note: Copper-based Algaecides such as the Long Life Algaecide or Pool Power Algaecide should not be used in Ionised Pools, with some brands of chlorinators or where high copper levels may be present.
Should copper be an issue, then we recommend Pool Algaecide or Supreme Algaecide. These algaecides need to be added monthly as a maintenance algaecide. When the pool is clear, it is advisable to test for phosphates and treat them with the appropriate dosage of Phosphate Remover to prevent algae from re-occurring.
*Caution: Flocculants can be time-consuming and labour-intensive to use.
When using clarifiers and flocculants, please monitor your pressure gauge and when the pressure reaches a high level, remove the cartridge and rinse clean.
At the completion of the treatment of your pool water, backwash and thoroughly clean your filter using Filter Cleaner.
