    Spa Calcium Increaser raises the Hardness of water in Hot Tubs & Spas

    • Brings Calcium Hardness level to an ideal range

    Spa Calcium Increaser is used to raise the calcium hardness in spa water. Calcium hardness in spa water should be maintained between 150-250 ppm. Low hardness levels could caused the spa water to be corrosive which may result in damage to the spa surface or hot tub equipment. Lower levels also cause foaming caused by soft water

    Directions for use:
    Read the entire label before using.
    1. Test spa water for Calcium Harness level
    2. Compare test results to chart to determine the appropriate amount on spa calcium 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
