we already figured that out... We are getting the fixture that goes with it...and I believe it has a built in fan. It is going to sit about an inch off of the top of the aquarium so if it does get hot I will just get a fan for cooling computure processors, or use one of my small fans for cooling off animal carriers. The modifications we are doing to the hood are extreeme. I dont want to completly get rid of the hood and the filter system, so we figured out a way to cut the hood in half and replce it with plexi glass or an acrylic cut to the original shape of the bow front, this will go from the filter all the way forwards. So the filter box will still be in the original hood.I was worried about heat too, but was told that that kind of cp bulb doesnt heat up that much.
I will still have a few shaded spots in the tank, like in the back under the filter, and since my live rock is raised up I have space under it as well. Shaz
