my tank has been up for about 7 months now and everything has been going good up until now. Im starting to get hair algae and all this brown slime is getting on my zoanthids and making them very upset...its pretty annoying because zoanthids are my favorite coral. not sure what would be causing this because it seems like this is something that happens when you cycle the tank.
as you can see this brown crap is making my candy apple reds all mad...same goes for other polyps as well
