Ok ideas to run by you... Instead of doing a glass wall to create land i was thinking of using PVC egg crate to angle the land at a curve. Then using a mix of rocks and planted dark aquaria substrate to create the underwater layer and the first above water level. This will allow me to grow plants on the underwater wall. It also creates a moist under layer for the land portion. I can stabilize the PVC by sealing it to the walls and bottom of the tank and support it further with a large piece of drift wood. This will also give me about 25 gallons of water to work with for the fish, and the substrate wont harm them at all . What are we thinking can live here? Will this work?
