I wonder if any one has purchased & used the MuckVac advertised to clean your pond? It uses a garden hose attached to the vac & sends the debris & water back on to the lawn. I need a vac that will clean a small 250 gal. pre-form pond & that will suck the debris & water OUT of the pond... NOT back into it after going through a net filter like one I bought. The water went back into the pond & stirred up the sediment something awful & soon over-flowed the pond! Tossed that useless thing! Tried attaching a tube so the water would go out of the pond but then the suction wouldn't work unless the return tube was IN the pond water!
