Considering Epiweb for Cork Mosaic Tank

Hey guys - starting my second dart frog build.

I got here because I was considering doing another great stuff viv, but this time going with the "cracked mosaic" of cork bark with mosses and tree fern stuffed in the cracks.

Then I realized that this seemed like a terribly temporary way to build it, and that the stuffing would be rotting, falling out etc.

So now Im considering using epiweb in the spaces...any thoughts?
