I too am setting up a frag system this week and it will be a 65 g main with a 30 gallon sump. Setting it up complete with DSB, LR, carbon filtration, Skimmer, and will eventually put in a clean up crew and a few dither type fishes. Want a place to grow out the corals growing like crazy in my main tank so trading and selling to get my addictive fix for less.
