I have a 55 gallon with 2 busted sides. A large pane and a small pane. I'm not quiet sure on how to take a tank apart without busting the rest. So I've got this idea {question}. Can I cut 2 pcs of plywood. Say 1/2 inch or 5/8 to size. Fiberglass it or epoxy it. And put it in place of the 2 busted pcs of glass? Of coarse silicone all those edges and corners good. That's also leaving the frame. Using it as support still. I don't see why it wouldn't but never know
