Poolife® pH Minus balancer lowers the pH of swimming pool water. The ideal pH range is 7.2-7.6. Maintaining a pH level above 7.6 keeps your sanitizer from working effectively and can cause scale, eye irritation and skin discomfort. This product also lowers the total alkalinity of swimming pool water.
Test pH frequently and add this product if pH is above 7.6.
Use convenient dosage chart on product label.
Always adjust total alkalinity prior to adjusting pH.
