Duckweed Description:

Duckweed (botanically known as Lemnaceae) is a small, stem less, free floating, aquatic flowering plant. Duckweed grows across the world except in very cold regions. Duckweed does not normally grow in rivers unless there is a reduced flow of water. Generally, the reproduction rate of duckweed is astounding given the right nutrient load in the water. Duckweeds grow 20 times faster than corn and are able to cover 1 acre in just 45 days if left unrestrained!

Duckweed Removal

Many varieties of water fowl consume duckweed which in turn transports it to other water bodies (they transport the seeds on their feet, wings and in their waste). Although Duckweed does provide habitats for micro invertebrates, duckweeds are aggressive invaders in quiet waters so it is important to control them. If duckweed covers the surface of a pond, it will deplete the oxygen, killing fish and the submerged plants that will not receive the sunlight for their growth.

It is thought that duckweed can be used as a water purifier, as the plant consumes nitrogen and phosphorus from the water. Due to this nitrogen and phosphorus consuming quality you will find duckweed in many ponds that have problems with septic, agricultural and fertilizer run-off. But using duckweed for water cleansing is certainly a low tech and time consuming process and duckweed cannot get rid of pesticides, heavy metals or toxic substances. Also, as mentioned above duckweed can very quickly cover a whole pond, and is very difficult to get rid of manually once it is overgrown.

How to Identify Duckweed:

  • Duckweed is bright green and when full grown, it can form carpet-like groups.
  • Common Duckweed has 1 to 3 leaves measuring 1/16 to 1/8 inches in length.
  • Giant Duckweed has 1 to 4 leaves measuring 1/16 to 1/4 inches in length.
  • 1 to 6 roots may grow from each “leaf.”
  • Duckweeds are a stem-less and seed bearing plant.
  • It is commonly found along with other types of duckweed or water meal.

How Can CLEAN-FLO Help You in Removing Duck Weed?

Bio Booster – Bio Booster is designed to increase diatom populations and reduce nutrients needed by duckweed. Diatoms are very beneficial for water quality and increase natural food for fish.

C-Flo+ – Reduces organic sediment (muck) where duckweed seeds are deposited and germinate.

Winter Warrior – Unique cold water microbial product designed to reduce nutrients and organic sediments during the cold water months when traditional microbes are limited by temperature.
