Well since no one seems to have tried it. I took a 1" clear water pump a piece of flexible hose a piece of 1" pvc pipe and a 90 capped the end drilled a hole in the cap and 8 more in the pipe 4 three inches above the cap and 4 more 12 inches above the cap. Then hooked it up to the pump. Set the intake about 2 feet below the surface then proceeded to move around the pond pumping surface water down into the muck. I would shove the pipe down till I hit solid bottom then pull the pipe up about 3 inches and pump water down until I have a cloud of dark grey or black water coming to the surface.My pump seems to be adding some air in the discharge. So I held it under water so I can see the bubble pattern. When I push the pipe into the muck I get about 5 times the bubbles from the disturbed h2s.The clouds of muck and organic debris creates a nice bloom. Before I did this experiment I had about 4-5 foot visibility after a few hours I get a nice green bloom with about 24 inches of visibility.
