Myka,
AJ's is selling a T5HO fixture that you can daisy chain together. Comes in 24, 36, or 48" lengths and includes ballast. They are CHEAP. They don't include reflectors but they do include a cheap 6700k bulb. I modded one onto my coralife fixture with a Hagen GLO reflector. Added a Giesman bulb and it works to add some par. They are called SunBlasters and look just like the ones called SUN BLAZE shown here...
