Do you guys think a 40gal with overflow and sump would be good for a QT tank?
You could certainly use an AIO as a QT tank. Most people just go cheap because once you use a tank and dose copper and meds etc. they are pretty much considered only QT tanks from then on out. Same goes for the equipment used in them, most folks would shy away from anything that was used in a copper treated system for example.What about using an AIO as a QT tank?
