Received it on time and in good shape. Thank you.
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.
I STILL HAVEN'T RECIEVED MY PACKAGE???

Copper Sulfate Powder
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.
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.
Good price and USA company. I would buy from your company again!
Fast delivery.
