You don't need to go all out here. A simple tank size of 10 - 20 gallons will suffice for most people. If you have larger fish, then obviously you want to get a bigger quarantine tank. All you really need is a bare bones setup with the following equipment:
1. Some type of filtration (a hang on the back of the tank power filter will work, just use filter floss without the carbon since carbon will remove medication from the water, being counter productive)
2. Heater
3. A power head and/or an air stone for increased surface agitation
4. Aquarium test kits for pH, ammonia, nitrite and nitrate
5. Fish Net - don't use the same net for your main tank
There are 2 of my personal favorite methods that I adopt.
Permanent QT or Emergency QT.
Emergency QT.
This type of tank is quite favorite among reefers. This does not require a setup that is up and running 24/7. List of hardware is same.
In case you feel a need for a QT, just put together all the equipment and put water from your main tank in it and you are good to go.
Keep an eye on ammonia and nitrites and do water changes as needed.
This method will require relatively more water changes that permanent method as bacterial colonies are not established and thus require a little bit more attention from owner to maintain perfect chemistry.
There are few ways to shorten/cut the attention requirement in this process by adding chemicals like ammonolock or amquel that binds ammonia from being toxic to fish.
Another popular way to seed the tank is to keep extra filters in your main tank's sump and keep them seeded this way and when required pull them and use them in QT.
Just remember if copper is used in QT, those filters cannot go back to sump once QT is taken offline.
