QT sizes

I know we are supposed to try to use quarantine tanks that are large enough for the permanent placement of the fish. This is cost and space prohibitive for most. I have previously used 10g and 20g tall tanks to QT fish for a 75g DT. I am setting up a 220g DT after a several year hiatus from the hobby and am trying to plan my Q tanks. I am going to focus on fish this time (been in the hobby for over 2 decades and had plenty of reefs) so I will have some pretty active swimmers in my 6' tank. Do you guys think 20L tanks are big enough to use as QT for larger active swimmers or do I need to look into bigger QTs. I will stock DT with Red Sea sailfin, blue spot rabbit, powder blue tang, lunar wrasse, undecided trigger, harliquin tusk, and maybe a majestic angel.

I would have at least one QT bigger then a 20L, I have a 55 setup that a Achilles will be kept in Wednesday and he is less than 3". I'm going to try two emperor angels together from juveniles in my 220g after a 75g QT. I kinda depends on the ize you purchase and how many you plan on QTing at onetime
 
If you have room, a 30 or 40 breeder makes a decent QT for larger fish. I see no reason that a big rubbermade or sterilite wouldn't do the trick too, and they're very easy to store when not in use.

Even 80g+ rubbermades are under a hundred bucks.
 
A 29 gal has the same footprint as a 20L, but is taller. You could QT all of your intended stock in one of those; so long as you did it one fish at a time and kept their purchase size within reason.
