Water feels slimy or foamy; visible foam on surface when bubbles are on.

Safety first: Foam itself is not usually dangerous but indicates poor water quality.

• Rinse bathers: Shower before using the spa and avoid lotions or oils.
• Rinse swimwear: Rinse swimsuits thoroughly in clean water without detergent before spa use.
• Use defoamer: Apply a spa-safe defoamer product as a temporary fix.
• Adjust chemistry: Check and adjust calcium hardness and sanitizer levels.
• Partial drain: Drain and refill part or all of the water if foam persists.

Warning: Do not use household soaps or detergents to clean the spa; they will cause excessive foaming.
