I don't have that particular fixture. I got my fixture before one was available with T5 bulbs. T5's are all about the reflector. You want a high quality parabolic reflector over each bulb (individual reflectors). That's what gives T5 bubs their POP. A good reflector increases light output several times over a flat or rectangular reflector.
QT does not require any special lighting unless you plan on QT for all corals for a 30 day period. I generally QT them for a couple of days, if that before adding them to my tank. I do give them a good swish in aged tank water before placing them in the main tank too. Not sure it helps all that much, but it makes me feel better
