Black Friday Doorbuster Calcite (for Acid Neutralization) 1/2 Cubic Foot Series [06PKIh5J]

Acid waters in contact with Calcite slowly dissolve to raise pH on waters from 5.8 to 6.6 it should be backwashed on a regular basis and replaced periodically as it dissolves. As the calcite's calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
