King British Green Water Control clears green water fast and helps maximise oxygen availabilty for a sparkling clear pond.

Suspended green algae is present in all natural aquatic environments and in small quantities it is beneficial. 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, remove oxygen from the water at night and cause pH fluctuations.

Green Water Control works by causing the suspended algae cells to "clump together" and sink to the bottom of the pond. These should then be removed using a net or siphon. 

When to use Green Water Control:

  • If green algae appears on the pond lining

  • If pond water appears green

  • If filter appears to be clogging with algae

Size: 250ml


Shake bottle well before use. Using the pipette add 1ml of Green Water Control for every 9 litres (2 gals) of water. Alternatively, add 1 capful (4ml) of Green Water Control for every 36 litres (8 gals) of water. For best results the pH of the aquarium water should be between 6.5 and 8.5. 

Continue filtration during treatment but remove filter carbon. Repeat treatment every 14 days while problem persists. When water has cleared, remove dead algae from the bottom of the tank and clean the filter. A 10% water change is recommended after the problem has been terminated. Renew filter carbon. Contains Synthetic organic polymer.
