I don't know where this deep green mossy looking layer of weird thing that spread quite fast in my tank. They are really easy to clean out. but they grow both in deep shaded area and hi light area. Does anybody know what it is and is there a chemical that I can add in the tank to get rid of them without damaging my corrals and fishes. Thank you very much.
They are not hair algea, I know for sure because......I also have hair algea in the tank :))
