Guy's I've been following these posts with much interest cause I also have a leaky dam, I have one observation, wouldn't it work also if you connected the outlet of the pump to one arm of a Y valve, and a hose from the other arm of the valve into the DB-100 bucket, and run a hose from the outlet of the valve into the pond. If this worked then you wouldn't have to worry about clogging up the pump. The force of the water flowing thru the Y valve should create enough suction to draw the DB-100 out.
