pH Decreaser is used to correct pool water that is too basic or alkaline, where pH levels measure above the ideal range of 7.2 to 7.8 ppm. To decrease the pH level, add 1 lb. pH Minus per 10,000 gallons of pool water. This will prevent scaling, calcium deposits, and cloudy water conditions.
Dosage: 8 ounces per 10,000 gallons of water if pH is 7.6-7.9; 16 ounces if pH is 8.0-8.4.
