SpaGuard’s Spa Anti Foam gives spa owners an effective way to eliminate foam build-up caused by excessive amounts of body oils, soap, shampoo, deodorant, and other hygiene products left by bathers in spa water. Spa Anti Foam’s powerful formula instantly removes foam with just 1 squirt of the bottle, yet won’t disrupt your spa’s delicate pH level, making its use worry-free. This product is safe for use with chlorine and bromine-based sanitation systems.
