I've recently upgraded my lighting system on my 75 gallon reef to metal halide. This has left me with a 48" T-5 setup. I have it mounted in a hood for a 75 gallon tank, however you could very easily take it out and incorporate it into something else. I have two icecap 660s powering seven bulbs (I would have had eight but I couldn't fit them). This gave me a total of 5 watts per gallon. I have had excellent growth under this hood. The four day bulbs are about 6 months old, but the 3 actinics are about 1 month old. The hood does get warm when it's being used so I have two fans that I will include in the transaction. They would just need to be installed. I'm asking for $350 or best offer. Please no low ballers. Between the two ballasts, all the bulbs, endcaps and hood you're easily talking over $500.
