I actually don't have a display tank yet. I am transfering stuff from my 20H frag tank to a new 58 gallon frag tank this weekend as long as everything goes good. I got my Deltec skimmer late last week, and by next month I should have calcium reactor in house. I am hoping to get a good deal on a used tank, but if the right thing hasn't come along by then I guess I'll buy a new one.
