TropiClear Calcium Hardness Treatment 4 LB Bag

To raise calcium hardness in swimming pool water

Dosage: 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.
