I'm going to buy a 30 or 40 gal tank to put my corals in, due to the crazy bubble algae outbreak in my 75 gal tank. Ugh... I'm hoping that maybe if I wrap my tank with a dark sheet for a month or more, that maybe I can kill off the bubble algae. My fish most likely won't be happy. But if that doesn't work then I think I'll either keep it a FOWLR, or take that tank down and start over, or go back to having a nano reef tank which I find a lot easier than a bit system...as odd add that sounds. My 75 has never looked anywhere near as amazing as the 10 gal nano I had 8 years ago.
