First, I'm trying to get into the hobby on a very slim budget. And I looking at a couple of used tanks on Craigslist - one a Biocube and one a 54 gallon corner tank. The biocube comes with everything and the corner tank only comes with the stand and a wet/dry system (no pump). Any thoughts? I'm hoping to have just a few fish and maybe some corals until I figure out whether this is for me or not. Thanks. Lene
