Spa Calcium Hardness Increaser™

Brings calcium into ideal range

Natural Chemistry’s Spa Calcium Hardness Increaser is used to raise calcium hardness in spa water. Calcium hardness in spa water should be maintained between 150-250 ppm. Low calcium hardness levels could cause the spa water to be corrosive which may result in damage to the spa surface or equipment.

  • Brings calcium hardness level to an ideal range
  • Reduces cloudy water caused by low calcium levels
