Duckweed in a system

Anyone have any tips on incorporating a duck weed tank in an Aquaponics system?

I have an upright 55 gallon barrel that's setup as a swirl/settling filter. I was thinking of extending the outlet above the surface of the water several inches and trying to grow duckweed in the filter water. I may need to slow the surface water a little.

Anyone experimented with this?

From what I am envisioning, the swirl filter is a bad place for it as the water on the surface always has to exit the outlet if you don't want it overflowing the entire filter. So if you extend the outlet won't this just force the water level higher and make the duckweed fall out later than it would have?
