Algae and Blanketweed

Algae or Blanketweed is unsightly and increasing in waters due to nutrient concentration as a result of human activity and natural processes. It needs controlling to ensure water quality is clean enough for environmental, recreational

Waters should be treated sooner rather than later – Herbicidal treatment and mechanical removal are not options for controlling the algae problems or blanketweed control you might have in your lake. (Blue Green Algae and Blanketweed Filamentous)

At Aquatic Solutions we recommend algae control and blanketweed control using barley straw rafts and aeration, as they are natural environmentally friendly methods of controlling algae problems in UK waters.

Problems caused by Algae and Blanketweed:   

  • Impedes the flow into drainage systems
  • Blocks pumps, sluices and filters
  • Interferes with navigation, fishing and recreational activity
  • Causes taint and odour problems
  • A health hazard to humans, livestock and wildlife

How Barley Straw Works

As it starts to decompose it releases a natural chemical into the water which inhibits the growth of algae. The straw raft lasts for as long as the straw takes to decompose, usually between 4-10 months depending on water temperature. The effects of decomposition has no effect to fish or invertebrates within the lake, in fact oxygenated straw provides a good habitat to feed fish.

Other Controls

Here are some other methods for controlling algae problems in UK waters;

  • Dyes
  • Microbial Treatment
  • Introduction of Grass Carp (requires approval of the Environmenal Agency)

How Aeration Works

  • Aeration is the addition of dissolved oxygen to the water.
  • Aerators move large volumes of water and add oxygen to the water.
  • The second component of aeration is mixing and de-stratification.
  • Improves water quality by impacting on 3 factors:
    • Oxygen: aeration encourages aerobic digestion of nutrients by adding oxygen.
    • Nutrients: these are kept in balance through digestion and oxidation.
    • Temperature: mixing breaks down stratification adding oxygen to lower levels.
  • Introduction of oxygen prevents anaerobic digestion and foul odours.
  • Oxygen introduced at lake bottom inhibits phosphorus release from sediment.
  • Oxygen in water converts phosphorus to an insoluble form.
