Well you have to have the hose going down to the stone anyway, and
over the tank edge is preferred for that. Using flat stock it won't
really add anything to the tank over the size of the stone, so don't see
any advantage to outside.
Yes, I like this very much, because the other problems for this method
we've fairly well worked out, and moving the stone bypasses the
remaining sticking point or two from a flat horizontal line, making
everything non-critical. Can't get much simpler than stick a stone on a
hose down there and swing it around under the board, and pumps and
stones are known to be reliable for long periods. Not that other things
can't be made to work quite well, but I think that even after you solve
the little gotchas, it's going to be a lot harder for the next guy to
repeat your solutions accurately. Stone on a hose with a little
mechanics is simplistic enough that I think it'll be fairly easy for
anyone to build it up and get it working well..
