I was thinking about Jan's preference for gravity fed filters. In a way, we
have both. The pump pushes up through the barrels and the water then flows
down through the VF ponds and over the falls.

Well gravity does play a part in your set up obviously, but you don't have
a gravity fed filter, wherein gravity moves the water to fill the filter
because the pump is removing water from the filter. (But you knew that. ;o)
