FEATURES- Adjusts low calcium levels to prevent corrosion and pool surface pitting.
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.
DIRECTIONS FOR USE
Read entire label and use strictly in accordance with hazard warnings and directions.
Calcium hardness in pool water should be maintained in the 175-275 ppm range. Never allow calcium hardness to remain below 100 ppm. Add HARDNESS TREATMENT directly to pool water by scattering it over the water surface. Do not predissolve this treatment as heat is generated when this product contacts water. Use a surface compatible brush to brush away undissolved granules off pool surfaces. The addition of 4 lbs. per 10,000 gallons of water will raise calcium hardness approximately 40 ppm. The addition of 10 lbs. per 10,000 gallons of water will raise calcium hardness approximnmately 100 ppm. |
