* Helps prevent etching and scaling due to low calcium hardness

* Easy to apply ( no mixing)

* 97% active ingredient ( calcium chloride)

Low calcium hardness can cause pool water to become corrosive, resulting in damaged equipment and surfaces. 

Directions for use:

1. Use test kit to determine calcium hardness level

2. If level is low, add Calcium Hardness Increaser directly to the pool by scattering it over the surface of the water. 

3. Use 1 lb of Calcium Hardness Increaser per 10,000 gallons to raise level 10 ppm.

4. follow dosage chart on bottle to determine amount to be used.

Note:

* Do not predissolve before using

* Use pool brush to mix up any undissolved material lying on the pool surfaces

* Do not add through skimmer. Add directly to pool water.
