    Copper Sulfate

    Our water fountain has been green for years. Even when we bleached it. In less than eight hours of using two tablespoons of copper sulfate and we had clear water, and all of the moss and green slime were cleared sway.

    Not what I ecpected

    I did not expect to receive such fine powder. I would have preferred larger crystals that would be easier to spread in our retention pond.

    Poor packaging

    You wrapped the bag of the product tightly in a USPS envelope. Usually, I can cut the USPS envelope with scissors. In this case, that also cut the bag of copper sulfate. It ended up spilling all over the work bench.
