Evolution Aqua Stop Blanketweed 4kg
Great product got rid of the initial problem of blanket weed and have continued to does monthly and hasn't come back. It took 4 weekly doses to completely get rid of it in my pond so be patient and the overall result is fantastic. It does leave alot of dust at the bottom of pond but nothing a pond vac cant solve. Pricey but much better than cheaper alternatives.
Excellent product. Tried several products with not to good results but this does what is says. No more blanket weed.
