Foaming Water Problems

Several factors can contribute to foaming in pools:

Soft water; low calcium hardness levels.

High TDS levels.

Lotions, oils and animal fats in the water.

Poor water balance.

Low grade algaecides. 10% polymers.

Tile cleaning phosphates.

Use of aeration (air jets) in biguanide treated pools.

Correcting the above conditions can reduce or eliminate foaming. Anti-foaming agents are available.
Chitin products like Sea-Klear can prevent or eliminate foaming from occurring. The Natural Chemistry line of enzyme products are also very effective anti-foam agents. Sometimes balancing the water and chocking the pool can remove the foaming.
