I built a frame out of Aluminum. 1" L angle for the width of the tank and 3/4" L to hold the 1" together. Used aluminum rivits to hold it together. I did 4 pieces in width as I also mounted the power supplies in the canopy. After all was assembled, spray painted it black plastic coat. Added 2 1x2 inch pieces of wood inside both ends of the canopy for the frame to rest on, this gave me the ability to move the lights forward and aft as well as tilt them slightly if I want to give a better angle on the aquascape. I don't have pictures to upload from here but will try to get some later tonight.
