Wow yours is complex and awesome!!
I just went with a water dish for the tomato frog and a part of the bottom glass and siliconed off for water for my Gray tree frog, filtration is way too advanced for me right now.

I'm definitely getting way too into this whole vivarium building thing but my bank account hopes I don't get to that size/difficulty level for a while haha!

Your plant options with so much more space make me jealous, it's going to look great once they're all planted!
(ps the architect/contractor bit was really funny and relatable!)
