The cheapest fastest way to set up a QT
is to get a small (10 or 20 gallon) aquarium and hook up a bubble filter and a heater. You could probably get away with something less the $50 for the set up. Catch the tang and put him in there and do frequent water changes to keep the water quality good. Ideally, you would have the media from the bubble filter soaking in your sump for a while to allow it to build bacteria. Since time is of the essense though, you would have to use water changes to keep the quality up.
, you need to remove the fish from the rest of your inverts and coral to effectively treat it. Fortunately, you only have one to worry about. Could be a lot worse . . . .
