Water clear then develops a reddish hue

Indicates a significant amount of dissolved iron in the water.


Small amounts of dissolved iron (and/or manganese) can be removed with a common water softener. The water softener manufacturer should have several models that list the amount of iron removal in grains per gallon.

High amounts of dissolved iron (and/or manganese) can be removed using a properly rated iron (and manganese) treatment device. Cartridge type devices are available to remove amounts of iron (and manganese) less than 5 milligrams per liter (the same as 5 parts per million).
