So, what I was thinking about doing was building a waterfall system with a small stream maybe for AGTF. What items can I use to build the waterfall out of that are safe for the frogs? I want to use foam and some type of adhesive material that is ok for moist environments without killing or making my frogs ill. I will be using a filtered pump and then have the water under the substrate by using the honeycomb light panels, and screen mesh with some type of other material to make up the rest of the bottom, either reptile carpet or Eco dirt. Any suggestions would help me out quite a bit! Thanks!
