Calcium Hardness Booster

It is important to keep your pool water in balance to get the most effective use of your chemicals. Test daily to ensure that pH, total alkalinity, calcium hardness and cyanuric acid (stabilizer) are within the correct levels.

Calcium hardness is an integral component of water chemistry. Soft fill water can cause low hardness levels, which leads to the corrosion of pool surfaces and fixtures. 


  •  Raises the hardness (calcium) level in your pool to the ideal range
  •  Prevents water from becoming corrosive and damaging your pool’s plumbing and heater
  •  Stops staining and etching of pool surfaces caused by low hardness levels
  •  Great for use in areas where soft water is a problem
