Hello and welcome to the frog forum! I have red eyed tree frogs and I absolutely adore them! They have big personalities and are so photogenic.

Honestly, it seems like you're overthinking this a bit. I do a drainage layer, either using leca, hydroton or something of the sort, then put a substrate, like abg mix, that can handle a slightly higher humidity. I run an airline tube in the drainage layer and behind the background as I build it and then just siphon the excess water out whenever I need to. Microfauna in the form or isopods and springtails are very helpful because they break down any vivarium waste. I've had tanks run for years with no hint of mold except during the first month, which is normal. You also have to make sure you're hardwoods instead of soft woods to help avoid mold. If I do a water area or water feature, I use the light diffuser egg crate sheets to lift my substrate.

Here is a good thread to give you some more tips - http://www.frogforum.net/showthread.php?t=32167
