Green Lightning Blanketweed Remover

"Thankyou for sending out our pond treatment so quickly and I am pleased to advise that has already been incredibly effective...."


"I have been using green lightning over the past 2 years having tried just about every other product on the market to control algae.

When the pond was at a stage where one could not see the fish for blanketweed I decided as a last resort to try this product.
Needless to say it was not a miracle cure immediately.  However with a couple of treatments I could at last see improvement.

I now use this on an average twice a year with excellent results. The fish,   a couple of which I have had for 18 years,  are thriving.  This year the fish have bred and we now have 5 young ones which are coming on very well.   So thank you 'Green Lightning'"

Dear Gavin
"I cant thank you enough for your product GREEN LIGHTNING which I have used to clear my pond of the wretched Blanket Weed. It has plagued me over the years and caused all sorts of problems with the pond equipment. It has been a year now since I purchased your GREEN LIGHTNING and the pond has been clear and the 'devils weed' has completley gone. I am a really happy customer and thank you once again for your great product and wish you every success in your business."

Mr C.Bedford

"Last year we had a huge blanket weed problem which nothing would make any difference. I found Green Lightning online and ordered some. It seemed expensive but we were desperate. At first the water went cloudy and we thought it was another failure, but we persevered. After the third treatment the water turned crystal clear. The blanket weed turned spongy and just fell away. We are still using the original pack and the water has remained crystal clear. I am so glad I found Green Lightning! I highly recommend this to anyone with a pond!"

Blanketweed - An explanation.




Spirogyra Adnate

Blanket weed (Spirogyra adnate) is one of the most prolific aquatic weeds known to amateur and professional pond-keepers in the U.K. In America it is called Long String Algae. This description is pretty accurate because in effect Spirogyra is not a plant but a filamentous algae. There are several other aquatic weeds which are also filamentous algae and the most prevalent of these are Cladophera, Rhizoclonium, Vaucheria and Ulothrix (Ulothrix is a Chlorphyte like Spirogyra and looks very similar)

The cellular structure of a cellBlanket Weed is a long thin filamentous alga, which like Ulothrix thrives in ornamental ponds. As can be seen from the microscopic observation, the cells of Spirogyra are characterised by helical shaped chloroplasts which give the weed the pronounced green commonly associated with Blanket Weed. Its growth is increased by bright sunlight and shallow fast running water so that it will be found in water-falls and unshaded pond areas. In ornamental ponds which tend be stocked with fish, the tendency to overfeed causes additional fish excrement which contains nutrients favoured by Blanket Weed particularly nitrates and dissolved ammonia. This means that apart from normal growth by photosynthesis the weed will grow even faster.

Spores releasing
The spores of Spirogyra can be preserved in the dry state for many years and come back to life when put into water. Ponds can be free of Blanket Weed for years and suddenly become infested. Pulling weed out actually releases spores produced by conjugation (see photo - bottom left), which then produce even more weed.

The proliferation of Blanket Weed is due to the fact that it grows very quickly in sunlight and if left unchecked can cause serious oxygen depletion in ponds. Additionally it can also cause stress to larger fish that find it an obstruction.
