None in the pond but lots of it in the deck
pondlets which only have tadpoles and snails.

In the biggest deck pondlet the azolla seems
to be crowding out the duckweed. I take several
handfuls out a day.

Azolla can be a pain. I had it take over a shallow
water bog once and it all up and died once
the water temperatures got too hot. Duckweed
seems to be made of sterner stuff.
