Crystal Blue Copper Sulfate Algaecide - Granular Aquatic Grade Copper Sulfate for Pond Algae Control - 5 Pounds

This stuff is awesome!! My pond was getting so over taken we could no longer fish but this cleared it right up and didn't seem to bother the fish at all

I love this product. I use to open my swimming pool. It works well. Clears my water quick and helps opening my pool and getting it ready for the summer season. It’s a good value, water clarity is amazing, and removes algae quickly.

I was skeptical to use this on my lawn but it turned out great. I can see my little grass seeds sprouting back up after being covered with algae.

This pond blue works like charm. Helps to keep the pond looking clean.

This works better for our scummy pond than other chemicals we have used.

Took about a week but worked like a charm getting rid of the floating algae that had overtaken my pond I mixed a pound of it with hot water in a gallon pump sprayer and sprayed it on the algae 👍🏻

Works with constant application, that being said, very expensive Make sure you don't touch or breath product.
