T5 or PC for 65gal reef.....

PC lights can be used for now, but you will likely end up wanting to upgrade at some point.

Very true. The bug comes around quick. Im in this situation right now, i have 260 watts of PC and i find that its not nearly enough to keep the many corals that i wish to have. Im probably going to shell out another $450 on lights, and thats besides the money i spent on the PC's, and its been about only 2 months. I would suggest going MH if you really want the bang for your buck.
