Solus Spa Calcium Booster is used to increase calcium hardness in spas and hot tubs in areas with low levels of hardness. Low hardness will etch plaster and corrode spa equipment. Before adding Increase Calcium to your spa, test the water with a calcium hardness test kit. The ideal hardness level is 200-400 ppm (parts per million).
