So I upgraded my light about a month and a half ago. Things were great for 2-3 weeks. I was slowly acclimating the new light to the tank per the directions, and the corals looked happy, then a huge cyano outbreak appeared and covered all corals, they were not happy. I dialed the light backs and controlled the algae as best I could. All my corals closed up and have not opened in about 2 weeks now. The algae is starting to go away slowly and Beginning this week I dialed the lights down to the lowest blue light only but they still aren't opening. Did I fry them? Anything else I can do? Not one of them has opened in about two weeks. Toadstool, GSP, Duncan, clove polyps, hammer, galaxea, even the purple mushrooms look terrible! I'm afraid I fried them all with the new light.
