I think this is what I have in my one 29 gal SW tank. It looks black, and it keeps forming on the back glass of the tank. No matter how much I clean it, a week or less later it's back. I put a big stick airator in there to get some movement since I haven't gotten a powerhead for it yet, and they form even where the bubbler is.
I know that PO4 is the cause, but are they that harmful to the tank? Is there something I can do to control it other than chemicals?
