Currently I have about 60lbs of live rock. My tank has been running for a little over a year, with 3 damsels, a mandarin,and a clown trigger (recently added). As for the corals, I have a goniopora, pulsing xenia, various zoos, and mushrooms and most recently a maxima clam. I want to get rid of the damsels, but have been unable to catch them without tearing up the aquarium. I also have about 20 hermits and 10 or so snails. I realize that the refuge alone may not work with this setup because of not enough water flow, but maybe if I couple that with either a canister or wet/dry. The only reason I am skeptical about the wet/dry is because of the limited space that I have, and I definitely would like to have the fuge. Let me know what you guys think.
