Almost any rock will do, depending on whether or not you like the "stacked"
look of the flat rocks or the rounded look of other rocks. Either way,
you'll need a few LARGE pieces of flat rock to use as weirs (the flat stones
the water cascades off of). The reason why the use of slate was not given a
"rave" review is that some of it is actually shale, not slate. Shale isn't
too terribly removed from its oil deposit ancestry, and can leave a film on
your water. I'm really not sure how to differentiate between shale and
slate - maybe other folks have the same problem - and that's why they just
stay away from it. Also, the darker rocks have a tendency to show the water
scale more than lighter colored rocks, depending on how hard your source
water is.

Good luck -
