Green pond scum

How do you get rid of green pond scum?
Windsor County Vermont
Can you provide more detail or even submit detailed, close-up photographs? I'm guessing your issue is with (1) filamentous green algae, (2) duckweeds or watermeal, or (3) blue-green algae/cyanobacteria, but any would only be a guess without additional info. All float on the surface as green material that is sometimes referred to with terms like "scum," but each would be managed differently.
