Water pH is a critical parameter in the oxidation and precipitation of iron and manganese. For iron oxidation by aeration, the water pH should be at least 7.2, and ideally, maintained in the range of 7.5 to 8.0. If manganese is present, the minimum recommended pH is 9.5. Below that pH, air oxidation of manganese is quite slow.
