Several years ago, I built a basking box for my turtle that sits in the rim of the aquarium and has a ramp into the water. I attached the plexi glass sheets to each other using aquarium grade silicon, but I don't think that was the best option. It's holding up so far, but I'm thinking about building a new and improved one, but I'm wondering what the recommended silicon/epoxy/glue would be?
More questions to come later
