I have T5 over my tank and couldnt be happier. I run the Sunlight Supply-Sun Blaze 48" 8 bulb fixture( only running 7 bulbs due to overhang) and I am allmost all SPS. The only complaint I have about this fixture is the are no built in fans, so I built my own fan rack using computer fans and they are dead quite.
T5's all the WAY!!!
