Thinking I had found a perfect lawn I leapt in the air and landed in the water, too shocked to scream.

So there are three ways of getting rid of duckweed, two bad and one good. The worst way is herbicides. We don’t want nasty chemicals in our gardens and we don’t want to waste money on chemicals. The next way is mechanical removal. It easy and you really feel you are doing something. But the duckweed grows back in a few days. The best way is biological control. If you have a biologically balanced pond you will not have a duckweed problem. And to balance you pond you must stop fertilizers from leaking into the water. Then you make sure you have oxygenating plants and some nice fish.
