Brilliance Calcium Hardness Increaser raises spa water to the recommended level of calcium hardness. 

Size: 14 oz

All water contains some natural hardness and it varies by geographic region. Calcium Hardness is the amount of dissolved calcium in your spa water. It is important to maintain the correct level of calcium hardness. High levels of calcium can erode pumps and cause damage to the internal workings of your spa.

If the calcium hardness in your hot tub gets too high, the only way to decrease calcium hardness is to use the Freshwater™ Vanishing Act Calcium Remover bag, which can be found here.
