I need to build a divider for my plywood tank. I sealed it using liquid rubber, so I can't have anything abrasive that I would wedge in there that could scratch off the rubber and expose the plywood. I also can't use the magnet holders to keep them up like I do in my other one. I have previously used pipe insulation around light diffuser but a) it floats so it is easier to knock down and b) the rays like to chew on it. Anyone have any ideas for me? Let's see them, more than one way to skin a cat, hoping someone has something that will only take me 1 home depot trip and an hour of work to get in there nicely, and the cheaper it is the more beers I can buy.
Thanks.
Thanks.
