Who uses quarantine tanks?

[Lance]

I QT all fish and inverts. Never want to go through Ich in the DT again! (The QT is a permanent set-up with live rock, sand bed, HOB filter, etc.) All new fish go in here for 3 weeks. If I spot a problem the fish goes into a 10 gal treatment tank, and is treated accordingly. This way new healthy fish have a decent place to spend their QT time. If treatment is required, the treatment tank is set up with seeded filter media for the HOB and a few pieces of PVC hiding places on the bb. I haven't been QT'ing corals; just a dip with Seachem Reef Dip.
