All great suggestions guys, thanks. I think I want to cover the inside with plexi and glass like you guys suggested but my dad seems to be worried that the glass will crack from the weight of all the planting I'll be doing on top of it, though I know that won't happen because it will be sitting against the wood and people plant in all glass vivs with no problems all the time.
Thanks for the other chemical suggestion Don but I want to keep this as cheap as possible, I don't have a lot of doe right now and plan on spending all the money I DO have on the materials for the actual build, not waterproofing the tank since my dad thinks he'll be able to get the plexi, glass, and silicone all for free.
And thanks for the build suggestion Ginger, I'm thinking about doing that as well, building hills up on the sides ands back and leaving the front middle sort of lower, maybe adding a communal pool there at the end of a water fall? I'm not 100% yet, I think I'm going to draw up some plans before I even start the build so I can get a good idea in my mind beforehand. Also Ginger, any plant suggestions you have would be great for me, I know nothing about plants and I want this viv to really pop with color and texture, and I know you have a green thumb.
What do you guys think about an escape-proof divider with two lids so that I can attend to the needs of each side separately without worrying about frogs escaping while I'm providing food, doing a water change, or any other miscellaneous action inside the viv? Any thoughts or suggestions on this would be a great help as well.
