Quarantine tank help

[mb5322]

So I'm an idiot and took my quarantine tank down, then decided I wanted a certain fish from divers den. I assumed it would be ok this one time. Well 3 days later I have an ich outbreak. My question is I don't have time to cycle my quarantine tank to put them in. Can't treat the DT because of all my corals. How can I safely put them into quarantine? Tims? Prime?

I'm setting my quarantine back up as I type this. Just don't want to lose anyone.

I have never cycled my QT.
I simply change 10-15% water each day.
I vacuum out any uneaten foods or wastes.

just take some media or good size rock from your DT and add it to the QT. instant cycle.
make sure the media/rock doesn't go back in the DT after treatment is done. chuck it or keep the QT running for future use.
