Koi Know How - Using algae controls

Without doubt, nuisance algae tops the list of UK pond owners' complaints. Green water needn't be a problem for any pond owner who has recirculating water in their pond since ultra violet units (adapted from the food processing industry) have been introduced to the pond and aquatics industry.

• Algae problems in koi ponds have risen to become one of the koi keeper's most common complaints.
• Interpreting the label Nuisance algae will usually take one of two forms; green water and filamentous algae known as blanketweed.
• For example, if a pond has benefited from a UVc, clearing it of green water, then blanketweed will proliferate, thriving in the clear sunlit pond water enriched with nutrients.
• Description of the product Volume of pond water treated Course of treatment Warnings or precautions Price Description of the product Scanning across labels of different products for blanketweed, various claims are used such as 'controls', 'clears', 'deals with', 'reduces' and 'kills'.
• Blanketweed treatments that 'control' or 'deal with' blanketweed growth may use a combination of dyes that turn the water blue, thus shading algae from its valuable sunlight thereby reducing its growth.
• The label of a treatment will specify the volume of pond water that it will treat (in litres and gallons) and this can be used to determine how many treatments you may get out of each pack.
• Some products state 'has no detrimental effect on fish and plant life' others state 'harmless to all fish', but may turn your water blue.
• The only aquatic herbicide on the market (Blanc-kit) is 'safe to use in ponds containing fish, emerged plants such as reeds and rushes' but may suppress or damage certain desirable plants such as water lilies.
