I did not have any large boom to skim the entire pond. I mostly waited on the wind to be of assistance. I used a pcv intake setup (picture attached) zip tied to a metal stake in the corner of the pond. The pvc wye with a ball valve constantly under the surface helped maintain pump prime.
At first the duckweed was incredibly thick. I would just put the trash pump on low throttle and let it slowly skim off of the surface. Once it had thinned out some i waited for the wind to help me. I used some 4 inch landscape boundaries (visible in the first post pictures) as small booms to sweep the remaining duck weed into the intake.
No chemicals were used. I may consider using if the duckweed returns which it probably will. It has only been a few days since the after picture. The duckweed was so thick I feared using any herbicide would cause a DO crash.
