Calcium Oxide

$57.50

Crystal Quest Calcium Carbonate Media is a naturally occurring calcium carbonate media. One of the advantages of Crystal Quest Calcium Carbonate Media is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Crystal Quest Calcium Carbonate Media, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces the potential leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry, and service flow, the Calcite bed will have to be periodically replenished as the Crystal Quest Calcium Carbonate Media is depleted. As the Crystal Quest Calcium Carbonate Media neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.
