Frag tank as a qt?

[sphelps]

Not as an actual QT for disease treatment but I usually use mine to house new fish for the first few weeks to monitor them and get them eating well before putting them in my display. Most treatments that are coral safe are not overly effective plus ideally you keep a QT free of items that can house parasites. Plus after treating a fish you'll likely want to change the water right out to prevent a build up of medications from further treatments on new fish.
