This tank used to be my pride and joy but moving it twice about 6 months apart left it with a horrible hair algae problem. Unfortunately I lost a number of my favorite corals. I'd get the water tested, and do it myself, and everything was always within acceptable levels. Finally I got desperate and just left it in darkness for 5 days straight. Then I turned on just the actinics for a day followed by three more days in the dark. Most of it got really loose and I was able to siphon it out. Finally I got a sea hare to eat the rest of it and all of a sudden it started looking much, much better. So much better that I went out the other day and bought frags of 3 different colors of Montipora capricornis to celebrate.
