Calcium hardness is a measurement of minerals in your spa water; low levels of calcium hardness could result in deterioration of metal components and presence of foam on your water’s surface. Increase your spa’s calcium hardness with this amazing formula that is highly effective and offers immediate results. Not only does Spa Alkalinity Increaser make your spa water crystal clear, it also helps prevent corrosion of spa equipment.

The ideal calcium hardness ranges for spas are between 100 PPM and 250 PPM for acrylic finish and between 250 PPM and 450 PPM for plaster finish; use Calcium Hardness Increaser when your water’s calcium hardness level goes below the ideal range, and enjoy crystal clear water.
