Bacterial

Iron bacteria are living organisms that feed on the iron found in the water, pipes, fittings, etc. They build slime all along the water flow path. Occasionally, the slimy growths break free, causing extremely discolored water. If a large slug breaks loose, it can pass through to the point of use, plugging fixtures. These types of bacteria are becoming more common in Canada. Tell tale signs of Bacterial Iron are a reddish or green slime buildup in your toilet flush tank. This type of iron problem is difficult to eliminate. You must kill the bacteria, usually by chlorination. It will be necessary to feed chlorine continuously to prevent re-growth. A filter alone will not solve this problem.
