Sanco Chemicals 222 Crystal Copper Sulfate Algaecide, 15 lb., Blue

I had floating mat in my pond in several locations and I apply crystal blue on the floaters and they began to settling and disappearing in the pond.

Did the job!

This is the product I needed for my pond. Price was right and the order came quickly.

It WORKS!!!!!!!!

Product is not as strong as competitors. I had to use twice as much to do the same job others have done over the years.

OK as listed

This is a good product and I searched all over for it. So easy to use and store.

Great product
