Lighting (MH who is the cheapest)

Josh, do you have one center brace or two over that 6' tank? I ask because I've seen 6' tanks with 2 bulbs, and unfortunately, the optimum position of the bulbs for the spread ends up being right over top of the braces, which results in two dramatic shadows cast into the tank. Just some food for thought... if I had two braces I'd give going to 3 bulbs some serious thought. If you only have one center brace in the middle then it's a non-issue, you're OK.
