  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..
