Again, in the picture above, that is the hole that will accept the pipe fitting that is attached to the pump. Water is drawn from the bottom of the pond and get dumped into the top of this bin.

All that was left was to cut and insert several layers of padding within the square part of the ducting hood. What I failed to photograph was the holes I cut in it (right where the square and tubular parts join). I strung some bylond weedeater "thread" through there to keep the filter pads from being pushed out of the tube.

Here's the pump, hard at work. That's roughly 5,000 gallons per hour and narry a surface ripple.
