Spa water is foamy with excessive bubbles that do not dissipate.

Safety: Handle chemicals carefully and follow label directions.

• Test and balance: Check pH, alkalinity, and sanitizer levels. Adjust to Beachcomber-recommended ranges.
• Use foam reducer: Add a spa-approved defoamer as a temporary measure.
• Water replacement: If foam persists, drain and refill the spa, and clean or replace the Microfilter.
• Rinse swimwear: Ask users to rinse suits in plain water (no detergent) before use.

Persistent foam is usually resolved by fresh water and better bather hygiene.
