I do not QT but I do dip corals with coral rx. I may be lucky because I do have good local fish stores in my area. The problem for me was this the lighting and water quality in my QT tank was never as good as the lighting and water quality in my DT. When it came to corals I found making the adjustment from crappy QT lighting to intense DT lighting was hurting the corals themselves too much. That being said every coral gets a good did before entering my system.

I have and haven't- Depends on the situation, both mine and the fish's. I haven't for quite a while now and so far so good.

When I started out with this expensive hobby...lol I lost almost all my fish to ick. So since then, I started to QT all my new fish, well if I buy the fish from any store, I QT, if I buy a fish from some of the guys here, I don't QT them bacause I know those fishes come in healthly already. I have a small 10 gal. tank that I use for QT. the tank only comes to live when I QT some fish, otherwise its stays off.
