How to clean a green pool
Over time, the clear blue of your pool can turn into a shade of green. While this is unsightly, it can be fixed with the right pool chemicals and help from your local Clark Rubber pool experts.
Read on for our advice on the causes behind green pools, as well as how to clean them and prevent this from happening again.
What causes a green pool
If your pool looks green, it is usually because you have a green algae spread.
Green algae spreads are the primary cause of this issue. Green algae occurs due to incorrect water balance, an abundance of phosphates (or carbon dioxides/nitrates), malfunctioning filtration and sanitation, or simply too much warmth or sunlight.
When this occurs, your pool starts to get green and cloudy, the filter requires more frequent cleaning, and the walls or floor can begin to stain.
How to clean a green pool
Step one: Use a Filtrite Leaf Rake to remove debris, leaves and dirt from your pool. Brush the walls and floor with a Filtrite Pool Broom, and make sure your skimmer and pump baskets are clean.
Step two: Ensure your pH level is between 7.4 and 7.6. Run your filter on circulate for two hours - you may also need to remove cartridge filters.
Step three: Add 2.5 litres of Filtrite Extreme Algaecide for every 50,000 litres of water in your pool. Make sure it goes all throughout the pool, then put your filter on circulate for two hours again. Remove cartridges if necessary.
Step four: Add 500 grams of Fitrite Pool Ultra Shock Plus or 15 litres of Liquid Chlorine for every 25,000 litres of water. Filtrite Pool Ultra Shock Plus should be pre-mixed in a bucket. Repeat the filter circulation process for 24 hours.
Step five: Your water should turn a milky colour, indicating the algae is dead. If this doesn’t happen repeat steps three and four. Repeat the filter circulation for 48 hours. If there is no change to the water, bring in a sample of your water to be professionally analysed.
Step six: Vacuum the sediment from the floor of the pool, then backwash your filter or use Filtrite Cartridge Cleaner, depending on your filtration system.
Step seven: Add Filtrite Algygone (one litre per 50,000 litres of water) and Filtrite Phosphate Eliminator to ensure the green algae stays out of your pool.
