I have a 75g and stand w/ a cannister filter......so far that's all I have. My funding dried up suddenly so my tank is going slow. I'm thinking of building a fuge/sump, and am trying to decide between an Aqua-c or an Euro-reef skimmer. My wife wants me to look into a Lee's skimmer. I would love to get some Tonga Kaelini rock, about 80 lbs and a 4" sand/crushed coral substrate. Once I get a skimmer, then things will start to pick up. As for fish, the list keeps changing as my wife and I change our minds.
