Duckweed is a sign of accelerating stagnation, and indeed will ‘Kill’ a pond if allowed to completely overgrow the surface. This occurs because it ‘suffocates’ the pond by preventing the exchange with the atmosphere of gases, especially oxygen .

Those whose ponds are affected with duckweed realise that regular mechanical removal is extremely time-consuming and hard work ! We can now offer a remedy. Aquatic Remedies Duckweed Control controls the growth of duckweed. It contains specialised microbes that consume the vital trace elements that the most common species of duckweed need to grow. It contains no pathogenic bacteria. It is a liquid formulation, and completely harmless to all fish, amphibians, invertebrate wildlife and other plants in the pond. It is not a herbicide.

Prior to treatment, as much duckweed should be removed from the pond as possible. Duckweed Control is then applied, weekly. The duckweed that has been removed should be taken away from the water catchment area of the pond, to ensure it does not decompose and re-introduce nutrients to the pond.

Duckweed Control should be used as part of a wider programme, designed to reverse the process of stagnation. Commonly, the bed of affected ponds has excessive deposits of organic sludge, which is usually black and stinks. This indicates that there is insufficient oxygen for clean aerobic breakdown of the organic material. Aquatic Remedies Microchalk will dissolve this black mud, so highly-expensive and messy dredging is unnecessary. Excalibio will block the growth of algae during the re-establishment of an ecological balance. Please consult us for more details.
