## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Right size granule
  

*by G***D on Reviewed in the United States on July 8, 2019*

This is the exact size granule you want for algae control. Light enough that it doesn't penetrate the algae and sink to the bottom yet large enough to resist some wind from blowing the powder back for you to breathe.

### ⭐⭐⭐⭐⭐ 







  
  
    Good Stuff
  

*by K***. on Reviewed in the United States on May 9, 2017*

We use copper sulfate to control algae in a 12 acre lake and use about 4-50 pound bags a season. Copper Sulfate from Amazon/Earthworks is always the right granularity we need/order and is shipped quickly. Earthworks customer service was great the only time I have had to contact them.

### ⭐⭐⭐⭐⭐ 







  
  
    Works for clearing pond algae quick and easy!
  

*by C***A on Reviewed in the United States on June 20, 2019*

We have a rather large pond (approx 2-3 acres of pond) and this Completely cleared up our algae problem around our pond edges!
