Setting up a QT is very easy to do. All you need in the tank is water and a place for the fish to hide. If you use water from your main tank it will cycle faster, you can either use 30 gal from your main tank or only half or only a few gallons, but the more water you take from your main tank the easier and faster it will cycle. You can use live rock for the cycle but then you should have no LR or LS if you plan on using it for a hospital tank because if you medicate any fish then you will kill the rock and sand. You can have like PVC pipe or lava rock for the fish to hide in. Thats basically how you set it up.
