hello,i want to buy just a small cheap fountain for like 20-30 bucks, and if i take it apart and use just the pump and tubes or whatever, how can i make a fountain in an iguana cage. i want to have in the corner,a tub of water sarounded by rocks,so you cant see it and have the water running down some bigger rocks into the little tub of watter.i hope you understand this,it was kinda hard thinking of what exactly to say.thanks.

Not sure if fountain is the right word, just a large rock with a hole in the top so water can spill out of the whole over the front of the rock. It will be approx. 7 feet tall, spillway approx. 2-3 feet wide. How many GPH pump do we need?
