Ah, now that's interesting. The pond with no fish is the worst affected,
the pond with a few fish has some duckweed and the pond with loads of fish
has none. Thank you, Donna. The only problem is that we want to keep one
pond fish free so that other wildllife are safe from their predations.
Life
is full of decisions!


Could you scoop up some of the duckweed from the fish free one and dump it
in the lotsa-fish one to give them a treat ?
