I have a small Sump that I never used sitting here. Its about 20"x10"x12" with a divider in the center. I also have a small submersible heater I'm not using. I really should set up a Quarantine tank for my next additions. What else should I get and would this be suitable as one? I also have some kind of lighting I think will work out too. I plan on using water from my tank to fill and do water changes in the QT tank. Since my numbers are really good, would this be okay?
