It should take some time for the seal to work but I don't know much about pure bentonite. Did he line the walls and the bottom? Everything leaks to some extent. This stuff isn't a plastic liner.

If he says 2 ft from the top, that's where he has built an overflow area. Or has built the dam 2 ft higher with the exception of one side area that is 2 ft lower.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
