I think you guys are missing the point. Obviously, you've never lived in a super tiny apartment where you barely have room for your dishes and your clothes, let alone an extra tank. It's probably not that the tank takes up too much room when it's set up as much as he doesn't have any place to put it when he's not using it. Am I right? The problem is, if you don't have an extra tank, you also don't have a hospital tank if you do have sick fish that need treated.....because some treatments aren't so good for your corals. You probably have extra 5 gal. buckets to mix or purchase water in, though. Maybe you could figure out a way to use one of those as a quarantine tank. Any ideas how to do that guys?
