Just a little feed back. I recently switched lighting on my 29 gallon from 65x2 PC to 150watt MH. I was torn between ordering MH or T5. While I am happy with my upgrade, in retrospect, I think the 24x4 T5ho catalina fixture I was considering would have left me with more options, in terms of amount of light as well as in bulb color. I cant seem to find a MH bulb I like after using the GE 9325s PCs. Just a little heads up for people facing a similar dilemma.
