This year our small garden pond is totally blanketed with duck weed. Is
there a remedy likely to be harmless to the inhabitants? Netting it out
seems to stimulate further growth!

An Oase SwimSkim will remove it eventually but they are not cheap and you
will need to empty it's container constantly at first. Once it's got rid of
most of the floating stuff it will only need cleaning out every few days as
it clears up any new weed, floating leaves, etc. Also provides water
movement and aeration.
