I'm def gonna upgrade, there's no question about that, but I'm gonna use my current fixture and simply gut it out and buy some t5 retrofit kits, would love to run 8 bulb setup but don't think I can fit that many in this hood...what would you recommend for low-mid light corals?? I may go led, but haven't decided, I love diy projects so if I go the led route, I'd be buying the diy led kits and fabricating a hood
