OK folks.... tired of looking at the 3 36" VHOs over my 40g breeder (36"long x 18"wide x 16" high). I've got a 250w ballast and bulb kicking around, and a Spiderlight reflector to house it in. Putting a small PC to either side of the reflector for actinic supplementation is a no-brainer. Here's the problem tho- since the Spiderlight is designed to run perpendicular (front to back) to the length of the tank, what do I do about mounting fans?
