These acid neutralizing well water filters correct pH between 5 & 7. The pH correction stops blue/green staining of tubs, toilets, and fixtures.
A combination of Corosex and Calcite is used to achieve a balanced reaction in differing flow conditions. Corosex dissolve faster and is best for high flows. Calcite produces a much slower reaction and works best for low flow rates. The combination provides even pH correction for homes with varying flow rates.
