Keep hot tub water in check. This product increases pH and Alkalinity to obtain the proper balance.pH and Alkalinity Up will increase the pH of spa or hot tub water. The total alkalinity of spa water
should be maintained between 80 and 150 ppm as determined by a suitable test kit. Maintain the
pH within the desired range of 7.2 to 7.8.
pH and Alkalinity Up should be used as necessary when pH is below 7.2.Note: For best results, dissolve granular products first by adding to a small, plastic pail filled with
