• CALCIUM HARDNESS INCREASER 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 175-275 ppm range
  • Never allow calcium hardness to remain below 100 ppm
  • Add this product 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
