Reefing newb
So my tank has been cycling since April but about 2 weeks ago I took all the water out to move it and set up my new tank stand, and build a rock wall in the back. I put all the old water back in the tank and have been cycling it since then. I know its going thru another cycle cuz its growing all this brown stuff all over the place. What would it be? And is it ok to be in there? I think someone said it was diatoms? Should I be doing something to get rid of them or will they go away on their own?
