So how does everyone maintain a quarantine tank? Do you just keep a spare empty tank and fill it up when you need to? Do you keep it running all the time? I have a spare 5G complete tank now, and I kind of feel like it would be nice to have a spare cycled tank already set up. But then it seems like a waste of my time to maintain an empty tank. I guess once it is cycled, it wouldn't really be any maintenance at all except to feed the bacteria. I could even throw a snail or 2 in to provide an ammonia source. What do you all do?
