Finished the egg crate thank god, stuff is a pain. But I figured I can use coconut halves for the pools. Just have to get a few from Mike over at glassbox tropicals. Just going to cover it with weed paper, and figure out what to use for the substrate in the water section. I'll most likely use ABG for the land portion. The top of the stream I'm going to make a drip wall and GS a piece of fern panel and small river rocks to make it look natural.
I have decided if I want to do 2 or 3 plants in tge back wall
