Whole House CALCITE PH NEUTRALIZING & FLOMAG FILTER Upflow Valve Fill Port (Removal Cap) 90% Calcite-10% Flomag

Regular price $475.00

Whole House Calcite pH Neutralizing Filter 
  1. Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not over correct under normal conditions. 
  2. Upon contact with calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces 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. 
  3. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. As the Calcite’s calcium carbonate neutralizes the water, it will increase hardness and a softener may become necessary after the neutralizing filter.

Raises pH of water to a non-corrosive equilibrium
Advantages of Calcite
Naturally occurring, inexpensive material
Low uniformity coefficient for maximum contact 
Slower Reacting for controlled pH correction

Advantage of Flomag
Flomag is corosex, which is an additive you mix with Calcite when treating very low pH level
used in 90/10 Ratio Calcite/Flomag. Corosex has 5 times the power of calcite to raise the ph
level of water.
