## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It works!
  

*by K***D on Reviewed in the United States on August 13, 2020*

Used this to control algae growth in our pond and it works perfectly.  The pond is about 4,000 square feet and about 3 feet average depth.  It is fed by a spring and has an outflow so the water in the pond is constantly refreshed and replaced. Using approximately 1 lbs of copper sulfate every week seems to prevent algae growth.

    Lowest price .
  

*by J***. on Reviewed in the United States on August 12, 2019*

Lowest price for stated purity and quantity. I do not know if it is 99% pure, did not send to lab. It works for my purpose that's about all I can say.
