Solve your acid water problems by installing a Calcite filter. Calcite is the same thing as limestone/calcium/hardness and will sacrificially dissolve, raising the pH (and your hardness somewhat). These systems will raise pH to above 7.0. Calcite is to be applied on pH between 5.5 and 7.0. Corosex media is to be applied for pH between 4.5 and 5.5.A chemical feed pump system feeding soda ash is to be applied for ph of 4.5 and below. You also apply this method if the water hardness is 10 grains or above. It all starts with a water test.Know your well flow rate before ordering any backwashing filter (read below).
