OK, so I have 3 RETFs in an 18x18x24 Exo Terra. I am pretty new to these guys, just an FYI.

For substrate I use coconut fiber (about 3-4" deep) , and top that with sphagnum moss so the fiber doesn't stick to the frog (and for humidity reasons).

I do not have live plants...

Anyways, I mist the tank a few times a day to keep the humidity up. Well, the substrate has gotten so wet, that you can actually see some standing water starting to surface. And to add to that, it's starting to get a smelly odor.

Any advice? Thanks.
