Hello, so I have been into the reefing hobby for about a year and a half now and about 4 months ago I purchased this 30 gallon tank and cycled it, and placed a few fish and corals in. I am at about the 3-4 month mark and all of the sudden this strongly algae began to grow very quickly and in a matter of days it is all over the tank and almost all of my corals have closed up. Just wondering if anyone could identify what it is and any suggestions how to get rid of it quickly. Much appreciated!
