Foamy water on the surface of the MAAX spa, especially when jets are running.

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

• Skim foam: Use a skimmer net to remove excess foam.
• Use foam reducer: Add a spa-approved defoamer as a temporary measure.
• Rinse swimsuits: Rinse bathing suits thoroughly in clean water without detergent before use.
• Balance water: Adjust calcium hardness and total alkalinity to MAAX-recommended levels.
• Partial drain and refill: If foam persists, drain a portion of the water and refill with fresh water, then rebalance chemicals.
