I have only cured rock in my tank and after six weeks it started to show up. A white mold like substance on just one rock. Now it has spread to another rock and is getting complete coverage on the first rock it also has a tine spot of green starting to show up today. This is week 7, I haven't seen anything dead in the tank and if it is the crabs eat up pretty quickly. (like a snail) So I don't think its something dead in the tank. It could be to much food but the substance is hard to rub off and doesn't have a feather or web like looks. Anyone HELP or should I just let it do its thing and not worry about it??????
