This form of iron creates sediments ranging in color from riddish-brown all the way to black and the precipitates formed will not go back into solution. Therefore they pose a great problem for water filtration systems. Water professionals often refer to this form of iron in water as ‘red iron’.
When testing for this type of iron, make certain that the test kit you choose can detect this type of iron. Sounds stupid for us to say that, but some iron in water test kits cannot detect ‘red iron’ and thus do not yield true total iron readings in water.
For a true reading of ALL the iron in your water, and not just the dissolved iron, we suggest the WaterWorks Total Iron Visual Test Kit which detects both forms of iron typically found in drinking water: Fe+2 and Fe+3.
