SpaGuard Calcium Hardness Increaser
by SpaGuard
SKU: 42636BIO
SpaGuard Calcium Hardness Increaser is used to increase spa water hardness. Spa water containing low levels of calcium will etch plater and corrode equipment. Low calcium levels will also cause spa or hot tub water to foam. Maintaining a hardness level will help protect your spa from these harmful effects.
