Spa pH Increaser raises the pH of water in Hot Tubs & Spas

  • Brings pH level to an ideal range

Hot Tub pH Increaser raises the pH of water in spas and hot tubs. Spa and hot tub water should be maintained between a pH of 7.4 And 7.6. Maintaining spa water pH in recommended ranges is key to proper balance. Regular use reduces corrosion damage to metal parts, pump parts and heaters caused by low pH. Improves the effectiveness of sanitizers and reduces eye irritation.

Directions for Use:
Read the entire label before using.
  1. Test spa water for pH level
  2. Compare pH test results to chart to determine the appropriate amount on spa pH increase necessary to make adjustment.
  3. With the hot tub not in use and circulation pump operating add required amount directly into spa water. Continue circulating water a minimum of 30 minutes
  4. Retest and adjust if necessary
