How the system works:
Calcite is a granular filter media used to neutralize acidic waters and raise the pH, making the water less corrosive. When water with an acidic pH of below 7.0 is passed through the filter bed the pH value is corrected enough to reach a non-corrosive equilibrium.
Calcite is dissolved during the service run and will need to be periodically replaced. To raise very low pH waters (4.5-6.0 pH).
