Spa Calcium Increaserâ„¢

Raises Calcium Hardness in Spa/Hot Tub Water

Natural Chemistry’s Spa Calcium 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.
