## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Worked for our pond.
  

*by M***5 on Reviewed in the United States on July 27, 2019*

Seems to have solved our blanket weed problem in our pond.  Not our duck weed- but the blanketweed was a much bigger issue for us.

### ⭐⭐⭐ 







  
  
    Didn’t receive size product ordered
  

*by G***P on Reviewed in the United States on July 12, 2019*

Ordered large crystals and received feed grade instead. Product is good but unhappy with what I received. Harder for me to use in my application.

### ⭐⭐⭐⭐⭐ 







  
  
    Great for clearing algae from ponds.
  

*by B***0 on Reviewed in the United States on June 24, 2018*

I used to clear algae from my pond. I highly recommend to all for this purpose and will buy from this seller whenever I need such products in the future.
