Cool, thanks for the offer... I'll keep it in mind.
As far as the lighting goes, I completely agree that 4 bulbs wouldn't be enough. My plan would be to ditch the reflector and use the bulbs, caps, ballasts that I have now while adding a couple more bulbs and figuring out the best way to reflect.
I've seen some setups use staggered bulbs as a way to get more light over a tank. Probably not ideal, but it's an option.
