Why Is My Hot Tub Foamy?

Foam in a hot tub is usually connected to dissolved contaminants such as soaps, detergents, lotions, cosmetics or other residues. Aeration makes those contaminants much more visible.

What to do first

• Check sanitizer and water balance.
• Clean or inspect the filter.
• Reduce the source of soaps and lotions entering the spa.
• Rinse swimwear thoroughly and avoid detergent residue where practical.

What does defoamer do?

Defoamer is useful for fast control of visible foam, but it does not remove the underlying contaminant load. If foam keeps returning, the water may need deeper maintenance or a drain and refill.
