Well I'm making plans to build my own plywood aquarium just had a few questions about the build. This will be my first aquarium build but I do have experience in reptile cages. First, what should I use to waterproof the aquarium. I've consider rubberizeit liquid rubber, pond liner, and epoxy. If you have any other ideas I'm open to them but i will say I really don't want to pay big $$$ when i can go buy a tank for the same price as the sealant. Second question is about glass thickness, is glass thickness the same as a all glass tank or is it different and how should i reinforce it?
