How do you get rid of the white foam that keeps coming back if you have bought and used two bottles of foam out and it still comes back and is there anything else you can use?

Answer 1

Clean your filter properly and you will not get foam. Defoamers just add phosphates adding to the foaming problem. Foaming in the pool can because by several different things. It could be chemical or equipment. First Equipment. Make sure you do not have an air leak on the suction side of the pump. Prime suspect here is the strainer lid gasket or "O" ring. Or possibly where the pipe or hose connects to the strainer of the pump. If you have an above ground pool the hose between the skimmer and the pump can be a suspect as well. The reason this is a problem is it will inject air back into the pool which agitates the water and can cause foam depending on what it going on with the water. Also make sure the return jets are pointed down. You do not want the return water to break the surface of the pool water. This can cause the same agitation and foam. Second chemical. If you have used an algaecide that is a quaternary ammonium compound this product is a foaming agent by its nature. If you use any algaecide make sure it says on the bottle non-foaming. The foam will fade as time goes on through dilution. The other chemical problem is low calcium hardness. Depending on the type of pool surface you should maintain a minimum calcium hardness level of 170 to 225 parts per million. Soft water will help the water foam up. Have your water professionally analyzed. Enjoy your pool!
