I've been reading up on t5 lighting to use on a 72 bowfront i'm in process of assembling. In the past i've always used metal halide over my reef, but their are some very reasonably priced t5 fixtures on ebay, thinking about an 8 bulb fixture that would have over 400 watts. It would come with 6500k bulbs but i'd switch those out with varying 10-20k bulbs. Anyone have success with t5's, and do you think it would work over my 72? Its 23" deep and i'm primarily interested in sps. The last time i kept sps was in a 40 under a 400 watt metal halide, and their growth was phenomenal. But the setup was a pure hillbilly rig and my wife hated the aesthetics outside the tank. Interested in hearing your experiences. Thanks in advance!
