Hi - thanks for the response - firstly, I have water lilies and such in
the pond and can't just sweep the hose over the top.

Sure you can. Lilies are tougher than that.

Second, if it
won't get all the duckweed, won't it just grow back in a few days
anyway?

It doesn't grow _quite_ that fast :-)

What would be the effect of adding some goldfish (to eat the
duckweed)?

That would help.

Would I need to keep the waterfall pump running all winter
(zone 4/5) if I did that so the fish don't die?

No. If your pond is deeper than a couple of feet (3' would be even better),
you should have no trouble with the goldfish, and the waterfall would be
_more_ likely to cause problems, rather than less.
