Product Information

AquaHydrotech Duckweed Control is part of AquaHydrotech's range of intelligent pond products.

Duckweed is an all too familiar problem for pond keepers. This thick green carpet of weed takes nutrients, light and oxygen from the water and as such effect the health of plants, fish and other pond life.

Duckweed Control works suing a special bacterial culture that binds key nutrients, and as such delays the growth of the most common varieties such as lemna minor. Once the duckweed has been eradicated, the treatment ensures that it cannot return, however the growth of other plants is unaffected.

Like most AquaHydrotech products, this treatment is safe for use with other plant life, fish and wildlife. It can not be overdosed, making it one of the safest treatments around.

Dosage: 25 mls per 450 litres (100 gallons) initial dose, then 10 mls per 450 litres weekly until duckweed disappears.


  • Shake the bottle well
  • Add 25ml for every 450 litres of pond water to a bucket
  • Mix well and pour evenly over pond surface
  • Use weekly to prevent re-growth.

500ml treats ponds up to 4500 Ltrs.
