REVIVE! 
So I just got a 72x30x24" and am looking in to lighting. I have a canopy with this tank so hiding those ugly spotlights is no issue. I don't need a TON of light, but would like a decent amount. Would 4x of the 10w lamps be enough? Should I go with 2x 20w lamps? Or more? Anyone tried anything different now that's it's been a couple months?
