It was pretty easy to install. On the bottom I used some 1" sections of 1/2" acrylic square rod every couple feet to keep it put. I welded the rod down about 3/4" from the back wall of the tank. It made kind of a slot for the background to slide in. I only used about a drop of Weld On 4 in case I ever wanted to remove them. I figured you'd never see them because here covered by sand anyway. Here it is before it was secured.
