The Power of pH and Alkalinity Up

Hot Tub Things pH and Alkalinity Up is the perfect solution to increase your hot tub water’s pH level as well as alkalinity. For best results, maintain your water’s pH level at 7.2 to 7.8. The total alkalinity of spa water should be maintained between 80 and 150 ppm as determined by a suitable test kit.

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.
