Answer:

Green does not usually indicate a response from iron in the water. Iron tends to make water more rust colored and red or brown color. If it is an iron problem, you can add any metal remover product that indicates for removal of iron. The exact brand varies from region to region and even at some stores. Because the water is green, I would be more inclined to believe it is algae related and therefore an algaecide may also be needed. You may also want to test (or have tested) the phosphate and nitrate levels which will contribute to green water.
