Features/Benefits

  • OMNI SPA CALCIUM HARDNESS INCREASER is used to raise calcium hardness in spa water
  • Low calcium hardness causes spa water to be corrosive and may result in staining, etching or distorting of the spa's finish
  • Plaster etched by low calcium hardness will become abrasive and uncomfortable for spa users
  • Rough plaster increases algae problems and makes cleaning more difficult
  • Calcium hardness in spa water should be maintained in the 175-275 ppm range
  • Never allow calcium hardness to remain below 100 ppm
  • Add this product directly to spa water by scattering it over the water surface. Do not predissolve this treatment as heat is generated when this product contacts water
