Spa water is foamy when jets are on

Safety first: Chemical handling requires gloves and eye protection. Keep chemicals away from children and pets.

Reduce foam:

• Test and balance water: Check pH, alkalinity, and calcium hardness. Adjust calcium hardness to manufacturer’s recommended range to reduce foaming.
• Use foam reducer (short term): Add a spa-approved defoamer to temporarily reduce foam. This does not remove contaminants.
• Drain and refill (long term): If water is old or heavily contaminated, drain the spa, clean the shell, and refill with fresh water.
• Rinse swimsuits: Rinse bathing suits in plain water (no detergent) before use to reduce soap residue.
• Clean filter: Rinse or replace the filter cartridge to remove trapped oils and debris.
