    Raises water hardness level while preventing foaming and equipment corrosion.


    • Increases water hardness
    • Helps prevent corrosion


    As Needed:

    1. Determine amount of product to be added. The ideal hardness level is 150-400 ppm.
    2. Turn jets ON to circulate spa water.
    3. Pour required amount into the water.
    4. Run filter for 1 to 2 hours.
