Similar size pond, same coverage of duckweed. How did you separate the duckweed from the liquid and did you return the water to the pond (California is water-challenged!)? I have not used a trash pump before, but I think the idea makes sense once I figure out the collection of the massive amount of unwanted weeds and how to filter the water back to the pond. Any advice is welcome.
I directed the trash pump output into an area where the water would flow back to the pond. Use a silt fence to block the duckweed. You will have to move the duckweed manually then, but it is a lot easier once it has dried.
