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.
