I got a bowl from work that is 4 in deep by 5 inches wide by 12 long so I might use that. Not getting the frogs till Feb and only putting plants in next month so I still have time to decide. I think I'm going to set it up using my idea and your idea and let it run for a couple days and see what I like. Problem with your idea is if I plant my bamboo in it like I want it will be in the front since I don't want to slope it to the back then it just makes it hard to change the water.

Although I could try to figure out how to slope it to the side.
