When acidic waters contact Calcite the media slowly dissolves and raises the pH.  Neutral pH values reduce the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing and maintain high service flows. Depending on pH and service flow, additional Calcite will have to be added.

As the Calcite’s calcium carbonate neutralizes the water, it will increase hardness and a softener may be necessary after the neutralizing filter.

50 lbs of calcite is 0.5 cubic feet of media.
