What kind of stone do you guys use or suggest putting around the pond bank? I am having a 1/2 acre swimming/fishing pond put in this June. The guy digging the pond wants to use #4 aggregate stone. He suggested aggregate over lime stone for the fact limestone has sharp edges and aggregate wound be better on the kids feet because it is more of a round edge stone. He also said it would match the color tone of the beige siding on our house. Does this make any sense? Number 4 is around 3/4 to 1 1/2 in size.
