pH Minus is used to maintain pool water in the ideal pH range of 7.2-7.6. It is a fine granular powder that dissolves instantly allowing you to use your pool at once. Depending on pH level, add pH Minus by sprinkling around perimeter of pool to lower pH level. If pH is 7.8 to 8.0, add at the rate of 12 oz. (3/4 lb.) per 10,000 gallons of pool water. pH Minus can also be used to lower alkalinity levels in pool water. 1-1/2 lbs. of pH Minus added to the quiet end of the pool per 10,000 gallons of pool water will reduce alkalinity approximately 10 ppm (parts per million).
