Thanks to all.
It's a small pond, but probably has too many plants that harbour the
weed. I probably need a plant free side section to wash the weed to.
The bicycle tube is worth a try - I'll try that today.
I had a water lily but it has disappeared. Can duckweed interfere with
other plants like that?
And yes I did use tapwater - so that wasn't a good idea after all!!
Found a message group in ponds and they seem to love having duckweed,
and their goldfish eat it. Mine don't get rid of it at all!
Found some stuff on duckweed on the web, but basically it says the
chemicals kill your other plants as well!

Anyone got a way of getting rid of duckweed. I've tried overflowing the
pond, but it won't all go because it's stuck in the plants. Tried
washing the plants - still comes back because I don't get rid of it all
I suppose. Do I give in and scoop off a bowl a day to create a little
space to feed the goldfish?

I use the garden hose on low setting, fine spray, to wash the duckweed out
from among the plants and into a pile into the corner where it is easily
scooped up.
Depends on the size of your pond I suppose - if its big enough for ducks you
won't be able to do that, but won't need to either!
Definitely a bit of duckweed is beneficial - it removes nutrients and
reduces light thus discouraging blanket weed.
