Foaming Water

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 "shocking" the pool can remove the foaming.
