plastic center brace and MH

[rocketlily]

To raise my light fixture on my 50 gal. I nailed 2 - 2 x 4's together (painted black), laid them across the ends of the tank, placed my light fixture legs on top of them. This raised the height of the light 3". I also keep a little 3" fan blowing between the top of the tank and the light.

The top centre brace does not get hot now.
