hi all. new to the board. Am heading in the direction of taking my 56 gal. to reef. (see tank specs) Was at my lfs today, and he is just getting in pc light fixtures. the 24 in has 2x55 watt tubes. under these lights, what would be a good bet as far as corals. i figure with sand and lr the tank actually has closer to 45 gal of water. also, i'm not yet running a skimmer, but would like suggestions as to a good one for this tank. i'd like to take the penguin filter out and use a skimmer in it's place. thank for any input. Oh, and by the way, this is a great board. I've been lurking around for several mos. now and have received a lot of good info. from you all. i look forward to sharing and learning. jwt
