I got pretty fancy with my enclosure, but it can be done as simple or as complex as you like. I've seen people use bioactive substrate in tubs successfully.
I am in the process of drawing out the background layout for my empty 55 gallon tank that I want to set up for dart frogs. I already have the bio active mix setup in a tub ready to go and hydroton for the base, this will be my first attempt at doing a foam back ground. Did you just goop a bunch on and start carving away with a razor blade until you got the rough shapes you wanted?
