What Can I keep with MH 20,000k bulbs?

[Richer]

I had over 500watts of MH over my old 33gallon tank (2x250w MH and 1x95watt VHO actinic). Just about everything loved it. I have a single 250w MH over my current 24"x24"x12" tank and everything is reacting quite positively to that as well. So I personally don't think going with a couple of 250s (via diy) is a bad idea... it would pretty much help you keep just about everything and probably be cheaper than that $700 light system. I built my old 2x250w system for under 500 bucks (including bulbs).
