TropiClear® Calcium Hardness Treatment 

This product is used to raise calcium hardness in swimming pool water. Low calcium hardness causes pool water to be corrosive and may result in staining, etching or distorting of the pool’s finish. Plaster etched by low calcium hardness will become abrasive and uncomfortable for swimmers. Rough plaster increases algae problems and makes cleaning more difficult.


Calcium hardness in pool water should be maintained in the 225-300 ppm range. Never allow calcium hardness to remain below 100 ppm. As a general rule, the addition of 6lbs. per 10,000 gallons of water will raise calcium hardness approximately 50 ppm.

Add TropiClear Calcium Hardness directly to pool water by scattering it over a large area. Do not pre-dissolve this treatment as heat is generated when this product contacts water. Use a surface compatible brush to brush away un-dissolved granules off pool surfaces.
