I've seen multiple DIY backgrounds and was just wondering if anyone has seen these sold commercially? Right now I use about 500lbs of rock in order to go up the entire back of the tank. I tried making my own out of styrofoam (I thought i was a pretty handy guy) haha but they never turn out the way I want them to. I'd imagine they are out there somewhere, but whenever I google it I find those stupid plastic tape on scenery sheets. Thanks!
