Wow, this is really beautiful. I'm wondering if you can fill me in a bit on the design and how the frogs are taking to it? I have recently purchased an Extra Large Exo Terra for my greys (10 females, 5 males) to live in and want to set it up with circulating water. I like the elevated plastic structure that you have here with a corner cut out. Do you have a filter and pump down in the bottom to clean and recirc the water? Is that working well and does this design reduce cleaning/maintenance? Also, where did you acquire the plastic grid and the tree bark backing? Looks great!
