We have that model as well. Its very good, ours is almost a year old, so its time for bulbs, this is my plan(more blue less white):
Geismann
3 Actinic+
2 Pure Actinic
2 Aqua Blue+
1 Midday

Instead of the 4 daylight 4 actinic the fixture comes with. We are also thinking of adding some blue lunar LEDs as the ones in the fixture are white.
Also as stated, some retailers list it as individual reflectors, which is false its one solid reflector. We haven't run into any problems growing anything under it. We have a Birdsnest up close to the surface, granted its considered the easiest SPS but either way it has grown and is doing fine.
