Spa Alkalinity Increaser™
Raises total alkalinity in spa/hot tub water
Natural Chemistry’s Spa Alkalinity Increaser is used to raise total alkalinity in spa water. Total alkalinity in spa water should be maintained between 80- 120ppm. As a result of the buffering effect of total alkalinity, pH, bather comfort, water balance, and clarity are more easily maintained.
Directions for use:
Read the entire label before using.
- Test spa water for total alkalinity level.
- Compare test results to chart below to determine appropriate amount of product necessary to make adjustment.
- With spa circulating pump on high speed, add required amount directly into spa water. Continue circulating water a minimum of 20 minutes.
