I use copper sulfate on my ponds. I buy it online 50#s at a time. I take a 10oz cup of copper sulfate and put it in a pump up sprayer with a gallon of water then spray it on the pond.
It’s been safe for the fish and other pond creatures because I never find any dead one when I do it this way. My Brother who is a Ph.d chemist is who set this plan up for me.
