Duckweeds

Duckweeds

A pond full of duckweeds; that’s a suffocating situation that quickly leads to odour nuisance or even fish kill. Ponds covered by duckweeds for longer periods of time often see their entire natural balance disrupted.

Biological balance disrupted

Below the duckweeds, nothing happens but degradation which causes the duckweeds to expand even further. This has a major negative impact on both the ecological system and the recreational value of a pond or other water structure.

Duckweeds is a collective name for various sorts of small, floating plants that have the ability to quickly cover water surfaces entirely. They are most often present in nutrient-rich (stagnant) water in ponds, canals and municipal water structures.

How to get rid of them

If your pond is filled with duckweeds, removing them is your only option. This is either done manually, or – in larger water structures – with a machine. In larger ponds and canals, the sludge bed can be removed as well, as this contains the nutrients on duckweeds love to feed.

Combatting duckweeds

By making stagnant water flow, the duckweeds are easily carried away as they do not attach themselves to the bottom. This combats new growth and makes removing existing duckweeds easier as they all float towards one place.

As soon as areas of water surface are opened, light can once again penetrate the water, enabling water conditions to start recovering.

Making water flow without consuming much energy is easy with the FLOW floating propeller mixers. These compact devices are easily put into the right place and fully plug-and-play.

FLOW mixers also enable temperature reduction and prevent stratification in larger water bodies, revitalising the water and preventing excessive growth of algae.
