Floating Weir Oil Skimmer For
Duck Weed Removal
The (FWS) Floating Weir Skimmer is a
perfect tool from removing duck weed from the surface
Duck weed or water meal can be removed with the Floating Weir Skimmer (FWS) which is a floating surface skimmer. If it floats freely and can move across the surface on a flow of water, the FWS is a great tool for water meal and duck weed removal. Pumping water from the FWS sump creates an equal flow into the skimmer mouth or waterfall / weir of the skimmer and into the sump. This skim or waterfall of fluid entering the skimmer carries loose floating materials (duckweed) or algae or weed into the skimmer.
If this flow is sent to a filter or strainer to hold back the duck weed the water can be drained back to source. Since duck weed increases exponentially, the removal of most of it allows you to keep up with it as opposed to trying to catch up.

Duck weed generally likes a eutrophic environment and calm waters and can double it’s numbers daily. There are biocides that will kill the water meal but their selectivity is lacking which means you can kill the whole pond or lake with the wrong bio treatment. Avoid when possible!
We find the largest skimmers (Model #FWS00A381 pictured left) are most effective since they have a 23” wide weir which acts as a mouth to open and allow the flow of water and duckweed into it. Big mouths can take big bites!
Golf courses are heavy hang out areas for duck weed, since they use lots of chemicals and treatments to keep the greens and fairways –well green. The big ponds attract the birds who can and do bring the water meal / duckweed in on their feathers and in their poop.

Common duckweed is a very small light green free-floating, seed bearing plant. Duckweed has 1 to 3 leaves, or fronds, of 1/16 to 1/8 inch in length. A single root (or root-hair) protrudes from each frond. Duckweeds tend to grow in dense colonies in quiet water, undisturbed by wave action. Often more than one species of duckweed will be associated together in these colonies. Duckweeds can be aggressive invaders of ponds and are often found mixed in with mosquito fern or water meal. If colonies cover the surface of the water, then oxygen depletions and fish kills can occur. These plants should be controlled before they cover the entire surface of the pond.
Duckweed colonies provide Habitat for micro invertebrates but if duckweed completely covers the surface of a pond for an extended period it will cause oxygen depletions. These colonies will also eliminate submerged plants by blocking sunlight penetration. Many kinds of ducks consume duckweed and often transport it to other bodies of water.
