### ⭐ 1.0 out of 5 stars







  
  
    Not effective
  

*by J***B on Reviewed in the United Kingdom on 3 August 2023*

Followed the instruction sheet to the letter. It had no effect whatsoever. The only way to get rid of blanket weed is physically- heavy duty brush etc. A waste of money.

    Did not work
  

*by K***R on Reviewed in the United Kingdom on 7 August 2023*

Dont use it it doesnt work. And the seller doesnt respond.

### ⭐⭐ 2.0 out of 5 stars







  
  
    This product doesn’t work
  

*by F***Y on Reviewed in the United Kingdom on 13 May 2021*

Had to wait a couple of weeks for the water temperature to rise. Kept pumps feeding waterfall and filter on but removed UV light as advised. Pond volume around 800 litres. Added packet to water and waited for the weed to disappear. That was around 5 weeks ago. At the moment there is still plenty of submerged weed that I was under the impression would be removed.
