Natural Chemistry's Spa pH Decreaser lowers the pH of water in spas. Spa water should be maintained between a pH of 7.2 and 7.6. When pH is too high (above 7.6), water becomes unco mfortable to bathers, sanitizers lose their efficiency, water may become cloudy and scale forms more readily. Dosage pH 7.3: 1/2 oz per 400 gallons of water. pH 7.2: 1 oz per 400 gallons of water. Directions Test spa water for pH level. Compare pH test results to chart on bottle to determine appropriate amount of Natural Chemistry Spa pH Increaser necessary to make adjustment. With the spa not in use and circulation pump operating, add required amount directly into spa water. Continue circulating water a minimum of 30 minutes. Retest, and adjust if necessary. Show more
