Our calcium hardness increaser helps prevent corrosion of exposed metal, plaster, tile grout, etc. in pool water that lacks specific mineral content.
Most water aggressively seeks minerals to achieve a natural balance.
Our Calcium Hardness Increaser provides a specific and economical mineral source to satisfy this need.

Our product will raise the calcium mineral level of pool water.
Maintain this level at 175 ppm in vinyl lined or fiberglass pools and at 240 ppm in concrete or plastered pools.

While the pool water is circulating, broadcast this product directly into the deepest end of the pool.
10 pounds of our Calcium Hardness Increaser in 10,000 gallons of water raises the level 80 ppm.
Test the water with a reliable hardness test kit or seek the advice of a professional.
