Straw will clear it. Don't know about Frogs though.

It's quite a large pond and barley straw hasn't helped in the past - or
not
enough, anyway. I suppose we could try dragging some clumps of it across
the pond.....

Are we confusing duckweed Lemna minor with algal blooms and filamentous
algae which barley straw does control.

No, what we have is duck weed. And it's worst on the pond we don't want to
put fish into!

How about using a vacuum cleaner made for cleaning swimming pools

It would clog up in seconds and take the small but desirable things with it,
like frogspawn, newts, dragonfly larvae etc!
