    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.
