  9. Calcium Hardness Booster Water Balancer

    Your pool water might look sparkling clear, but your water may also contain a concealed hazard to your pool equipment and surface - Low calcium hardness.

    Calcium hardness is the amount of dissolved calcium in your pool/spa water. If the water does not have enough calcium, it will scratch plaster surfaces. If there is too much calcium, it will deposit the excess on pool/spa surfaces and equipment.

    A low hardness level can cause corrosion of your pool's plumbing and heater as well as stain or etch your pool's surface. Maintain hardness levels to ensure lack of vinyl bleaching, loss of vinyl elasticity, and in concrete pools calcium hardness helps prevent pitting. Maintain Calcium levels between 200 - 300 ppm for Pools and Spas/Hot Tubs. Remeber to first balance your alkalinity, then pH level and lastly your calcium hardness. 

    TO RAISE CALCIUM HARDNESS:
    - Test your water and calculate how much Calcium Hardness Booster is needed
    - Mix with water and add to pool
    - Use about 1/4 at a time and wait about 6 hours in between
