Suspended green algae is present in all natural aquatic environments and in small quantities it is beneficial. However, when excess nutrients and light are available, algae in ponds can become thick, unsightly and out of control. It may also be harmful to fish because it can clog the filter, foul the water, irritate fish’s gills, deplete the oxygen in the water (especially at night) and cause pH fluctuations.

Green Water Control binds suspended algae cells into biodegradable clumps that sink to the bottom of the pond. Remove these clumps of algae using a net or pond vacuum. If left they can deplete oxygen in the pond and stimulate renewed algae growth. 

To help control algae growth, shade your pond from direct sunlight, introduce pond plants (which compete with the algae for light and nutrients), ensure the filter is working correctly and do not overfeed your fish. Never use fertilised garden soil in any planting baskets. Use Green Water Control:

  • When excess floating algae appears on the pond surface
  • If pond water appears green
  • If the filter is clogged with algae
