false backround and waterfal?

I wanted to create a tropical rainforest for some bumble bee dart frogs ive done some research and I get the gist, I was wondering if anyone here could go into detail and maybe post some pictures anything to help me. It's nothing extream it's a 20 gallon long tank that I wanted to decorate like a rainforest with a water effect and a drainage system. Any help would be useful.
Thanks,

which version are you talking about?
the one with the concrete and dye or the painted verison with dye

I meant to say false bottem and backround im pretty educated on the backround im interested in making a false bottem for drainage.

Egg crate light diffuser panel ($10 at home depot) supported with pvc pipes as colums worked well for me. check out http://www.dendroboard.com/ its loaded with information and tips.

hydroton covered with landscape fabric works too
