The *best* control I've ever had for duckweed is a simple
goldfish. One of my children won it at a school fair, and
I put it in my 180g. It ate duckweed around the clock,
and went from a little trim 1" to a whopping 4" round gold
ball in a few months when all the duckweed was gone.
Remember, this is ONE fish that not only ate a huge pile
of duckweed in a large tank (180g), but also went faster
than the (very high) duckweed growth.
BTW, he left the frogbit (Limnobium sp.) and Salvinia sp.
alone. I don't know if that's normal or not.
I can't establish duckweed again, so he's got to make do
with flake food. I can't get rid of him because he's
affectionately a part of the family, named "Swimmer #4".
