Worked for our pond.
Seems to have solved our blanket weed problem in our pond. Not our duck weed- but the blanketweed was a much bigger issue for us.

Didn’t receive size product ordered
Ordered large crystals and received feed grade instead. Product is good but unhappy with what I received. Harder for me to use in my application.

Fish kill
This product was not supposed to kill fish in your pond when used. I used approx. 1 quart and a half in a 1acre pond on Monday 6/8/20 and the next day fish started to die. It will kill weeds also but would not have used if I knew it would kill fish. Will not use the remainder of this order nor will I buy anymore. Cant give it any stars as it killed my fish which it was not supposed to do.
