I still make my own food. I find it cheaper and cleaner. I like to know what I'm putting in my tank. As for the lighting, you could throw a T5 retro kit over the tank as a supplement. You could put just blues in it and put one or two lamps in front and one or two in back. When I ran T5 over my tanks I wouldn't get any shadowing really. A friend of mine does that very things, and his corals are evenly lit. He's using radions and ATI T5 retro kits, so he still gets his shimmer too.
