Green clean

The product worked. It took a little longer than expected. My only issue was how far I could throw it . It didn't appear to affect the koi

Green Clean

easy and good. Problem was getting the container open the first time. I had to use a hammer and a stick of wood. There was also a red trigger that when you close the screw on lid, then to open it again you have to press the red trigger to allow the top to screw off. The red trigger was not in the box or on the lid.
