How to QT properly


New member
I have never used QT in the past, and was successful for all but the tangs. I will be setting up a new tank soon and have a 40B currently set up. I was thinking I might as well leave this up and running to QT my tangs. How do I QT properly ?

I want to do it right so I don't have an ich breakout. Do you just leave them in there and feed for a couple weeks or what ?
