$18.98 $18.58

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.

Use: pH and Alkalinity Up should be used as necessary when pH is below 7.2.

 For best results, dissolve granular products first by adding to a small, plastic pail filled with water. Then, apply the solution to the spa water.

  1. Determine amount of pH and Alkalinity Up to use.
  2. Make sure equipment is OFF.
  3. Add applicable amount of pH and Alkalinity Up to the spa water.
  4. Turn on circulation system for 1-3 hours.
  5. Retest water after 3 hours.
  6. If pH is still below 7.2, repeat steps 1-5.
