![]() ![]() Biofilm colonies can grow on various surfaces and once they grow on a surface are much harder to dispose of with chlorine or normal sanitizing chemicals. ![]() ![]() To remove biofilm you are going to have to brush down the pool liner thoroughly with a pool brush and handle. Besides white flakes from white water mold, a telltale sign of biofilm is cloudy water or a bad odor coming from the water. The best way to prevent biofilm is to maintain proper pool chemistry and remember to run your filter pump at least two hours a day to oxygenate the water. Body oils, lotions, dead skin cells, cosmetics, etc all can become the basis for a biofilm colony. Biofilm does not need sunlight to grow but prefers warm water. Unfortunately some colonies become chlorine resistant which means that you will have to use other chemicals and other means of disposing them if they are the cause of the white flakes appearing in your pool. If your flake has dissolved it means the white flakes are due to white water mold, if not then it is due to calcium deposits.īiofilm basically refers to a colony of bacteria living in your pool. After about 30 minutes you can check and see if the white flake disappears or not. To test if the white flakes are due to calcium or biofilm take a small cup with a white flake sample floating it in and add about 15 to 20 drops of bleach. Out of the two we recommend using a pool clarifier since our pool is so small it generally won’t take 24 hours, but you should use a fresh filter cartridge before you have used the clarifier to clean your pool. Pool clarifiers work by clumping the particles of debris together making it easier for your filter pump to clean it out. If you choose to use a pool clarifier instead you will need to run your filter pump up to 24 hours until the water is clear. When you use a pool flocculant you will see a cloud of debris at the bottom which you will need to use a pool vacuum to suck up. Flocculants work faster than clarifiers and take all the particles that are floating in the water and sink them to the bottom of the pool. If you want to use chemicals, there are two kinds that you can consider: clarifiers and flocculants. An effective way to do this is to drain about 1/4 of the pool using the release valve and refill it with fresh hose water.Īfter you have refilled your pool, run your filter pump two to three hours to circulate and mix the water. ![]() To reduce the calcium level of your pool one of the easiest ways is to add fresh water to dilute the calcium. This can happen sometimes if your water already has a high calcium level or if you super chlorinate the pool using a pool shocker chemical. The calcium hardness in your water should be balanced, if you are experiencing calcium scale deposits it means your calcium level is too high. The white flakes may be calcium deposits that have accumulated over time. If you see white flakes it is actually not paint but may be either calcium scale deposits or biofilm residue in your pool due to bad pool chemistry.Ĭalcium scale deposits occur when your water has too much calcium. This type of coating would not come off as flakes and float in the water and is much stronger than conventional paint. This isn’t the case because the outer coating is baked onto the metal during the manufacturing process forming a skin. They believed that it was paint from the white metal frame. In the past we have had customers coming to us asking why there are specks of white in the water. ![]()
