What causes foam in my hot tub?

Foam is typically caused by the buildup of body oils, lotions, cosmetics, detergents from bathing suits, and other organic contaminants in the water. While Foam Down quickly eliminates the foam, recurring foam may indicate that your spa water needs additional maintenance or a water change.

Does Leisure Time Foam Down affect my spa's water chemistry?

No. Leisure Time Foam Down is designed to suppress foam without significantly affecting your sanitizer levels, pH, or total alkalinity. It can be used whenever excessive foam appears without interfering with your normal water care routine.

Can I use Foam Down with any sanitizer system?

Yes. Leisure Time Foam Down is compatible with chlorine, bromine, ozone, and biguanide sanitizing systems, making it suitable for virtually all residential hot tubs and spas. Simply shake the bottle, add approximately ½ ounce directly to the foaming area, and repeat if needed.
