Duckweed.com.au is an information site about the uses and abilities of the Lemnoideae plants commonly known as Duckweed. Duckweeds or water lentils are aquatic plants which float on or just beneath the surface of the water, and may just be the solution for all your algal, waste water, ecologcial and feed problems.
 This is an actual visual comparison of Domestic waste effluent water, with photos taken before and after using Duckweed as the cleansing medium.
The “Before” sample was drawn from waters, adjacent to the Primary pond inflow pipe and the “After” sample taken from waters leaving the Duckweed pond via the outflow pipe (see Algal control photos).
The jar samples were taken immediately and simultaneously after the Duckweed had achieved full cover on the 1020 square metre Waste Water Secondary pond. |

Duckweed’s greatest asset is its ability to control the growth of algae by forming a blanket above the algae and therefore restricting available sunlight.
The reduction of nutrients have minimal effect on the growth of algae as algae has a far less nutrient requirement than that needed to sustain growth of duckweed.

With a protein level up to 50 % (surpassing that of Soybean) duckweed’s attraction as a food source is not surprising.
Duckweed as a food also has higher concentrations of the essential amino acids, such as leucine, arginine and valine as well as trace minerals, pigments and xanthophyll.

In a pond covered with duckweed, you can expect a decrease in common pollutants such as nitrogen, an increase in water clarity and water disinfection.
There will also be changes evident in the levels of ammonia, Tot K Nitrogen, Nitrite, Nitrate and Phosphorus.

While performing tests on duckweed in both a domestic and commercial environment it was noted that the duckweed attracted more and more frogs, with an accelerating abundance of aquatic life forms and substantial reductions in observed mosquito larvae.
Other life forms were observed drinking and frequenting the Duckweed Secondary Waste Water pond which was previously quite void of life.
