Doesn't take much. Standard fluorescent lighting or even the cheap incadescent lighting are fine. A small power head or even better, a small HOB power filter, or sponge filter. You can put the sponge filter or the media from the Power filter in your sump to seed it. Put in a couple larger PVC fittings for fish to hide in and you're set. You don't even need sand or live rock. I have live rock and sand in mine because I also use it for growing pods. In fact, it's used more for that than for QT. I do QT fish in it as well though. I just don't medicate them. I have mine full of Chaeto and it's full of pods.
