How do you make a rock waterfall?

Thanks for the posts unfortunately I'm on dial-up so will have to wait till I go to my brothers tomorrow to watch the video. I have a pool about half the floor space (see photo) that should be okay for an external pump I'm looking for a rock waterfall to fit in with the water substrate. The photo is a few months old so don't worry the water level is deeper and the tank not so bare (logs, bark and plant has been added).

I made one from styrofoam and cement, picture is attached. The styrofoam was free, quikrete+ acrylic fortifier was ~$35 for enough to make a few hundred of these (smaller less cost effective quantities are available). A few more details on how it was built are here: http://www.frogforum.net/vivarium-te...struction.html

That looks great UncleChester. I haven't decided on anything yet but I had an idea and would like to know what others think. What if I chisel a big stone to make it sink down in the middle and put another one on top do the same but chisel off a corner to make the water drip down. Obviously I'd boil the stones to remove any nasties.

If you have the ability to carve away at stone, then go for it! With pictures of course.

Be sure whatever stone you use won't adversely affect your viv. Living in limestone land I'm very aware that some types of rocks can raise the pH (much like cement), so it's something to check into.
