Advice on how to maintain an empty quarantine tank. I have a 24g qt fully cycled from a sponge from my sump. I have qt'd a couple of fish successfully and now I am placing them in dt. How do I keep my nitrifying bacteria alive in qt without any fish? Will the bacteria just survive or do I have to "feed" the tank with mysis or something. Also, I have a reef octopus hob skimmer on it- should I just turn that off when not in use?
