I took Journeyman's advice and bought a dewatering bag. Works GREAT!!!!

I'm now testing a larger homemade skimmer combined with a floating housing so I can take the skimmer to the duckweed. the wind has to blow the duckweed a certain way for it to work when mounted on my dock.
I'll post results and plans for the skimmer if it works better than the 6" skimmer I'm using now.
