Hi all! I am building my first bioactive vivarium for my dumpy tree frogs! I’ve probably bitten more than I can chew with this one haha, but it’s coming along slowly but surely...annnyways I made a waterfall, ending in a pond using styrofoam with a layer of spray foam on top.. I’m planning to grout/paint the waterfall part but I’m not sure exactly what to seal it with to waterproof it.. I’ve purchased LePage professional epoxy but then read online it is not good for anything in direct contact with water or submerged.. would clear silicone be a better option or both? I just want to make sure I don’t use anything toxic and I want to make sure I do this right because I’m only doing it once! There are so many things to factor in! Progress thus far!
