Corrosive Water Problems
Corrosive Water Problems

Acid, neutralizing filters are very simple ,water treatment, units that are intended to increase pH and add calcium thereby decreasing corrosivity. They consist of a tank filled with calcium carbonate (,limestone,) chips, marble chips, magnesium oxide, or other alkaline material. The ,acid, neutralizing filter is usually installed after the pressure tank.
