Calcium Booster -Leisure Time

Calcium Booster is used to increase calcium hardness in water that has low levels of hardness (Soft water).
Low hardness can corrode the equipment, cause foaming and damage acrylic spa or permenant wrinkling in a vinyl lined spa.

The ideal hardness level for a vinyl-lined spa is 150-400 ppm. 32 oz. One half ounce of Booster raises hardness 7 ppm in 250 gal of water.
