Calcium and magnesium will differ significantly between the two tanks. pH might wind up quite different, as I've set the QT up in the basement in the laundry room (near that big old drain in the floor
) and the air is quite different down there.
Otherwise, everything else should be pretty similar. The gent I got the setup from gave me everything he was dosing, so I can adjust the hospital tank if need be (though I shouldn't need to).
I'll acclimate the fish when I move them from the DT to the QT, and then to the new DT.
