It did not take much thinking for me to decide to set up another sw tank. It has been almost 3 years for me so I want to pick you brains. I have a 55gal. no lights yet, but i do have a magnum 350 canister, an undergravel, 3 powerheads and 2 biowheels. is that going to be enough? Should I ditch the undergravel and go with live sand? and what about a skimmer? I have used Seaclones skimmer before and it seemed good. What do you recomend? And the last question is I will most likley keep this a fish only tank with a couple clowns a yellow tang, a goby, and I might get a crab. So is live rock and sand a good idea or should I just go with base rock and stuff? I might go farther in a year or so with some corals so I do not want to have to start to set the tank up again then.Thanks
