You'll do better to use glass for the baffles. Silicone doesnt stick to plexi very well, some have luck, but not myself. The single pane sheets work fine, but they are a little thin. Measure the inside of the aquarium, be as exact as you can. You can do this from the outside of it. Looking into it. Then go have a glass shop cut you some pieces. Look for silicone wich does not have any mold or mildew resistance. 100% pure silicone. Likewise, if your not sure of what your looking at, just get the the aquarium grade stuff. It's more expensive, but only a few bucks, and you'll have piece of mind. I have used both and find no difference in them.
