We are putting in a small pond with waterfall/stream. All the literature
that I have read recommends sealing stone in the stream with a foam. Every
foam product that I can find says to not use under water. What kind of foam
are they talking about.

Depending on your waterfall, rock used, flow rate, you may get away with
not using foam at all. I did. Black foam as mentioned, once dried is
non-toxic. ~ jan
