I have a 90 gallon reef tank that has been set up for 8 mo. It has cycled. We have fish and lots of coral. Almost overnight a bloom of brown algae looking stuff has covered everything. The rocks, sand, and even pumps. I did have my protein skimmer off for a week because we were treating red cyno algae. It's back on now. All my levels are fine but now my corals are not opening. They all look like they are dying.
