If you happen to have goldfish or similar in another tank, growing duckweed on the tanks you can is great, because you can feed it to the goldfish. It's wonderful food for them - very nutritious.
I am now growing as much duckweed as I can on my NPTs and feeding it all to the goldfish. They love it, I love it, we all love the duckweed. (Agreed it can easily get everywhere if you're not careful, though).
