Full Description

SpaGuard Calcium Hardness Increaser - 12 Ounces

Calcium Hardness Increaser raises calcium hardness in hot tub water. The desired calcium hardness level in hot tub water should be 100 to 200 ppm. Low calcium hardness, below 100 ppm could cause spa water to be corrosive which may damage spa surfaces and/or equipment.
