Ponds, Algae and Copper Sulfate
My acre pond has more algae in it every year. The local nursery recommended adding copper sulfate to kill the algae. They said it doesn't hurt the fish. Can anyone verify that it is safe for the fish, ducks, wildlife and, more importantly, us. Our cows drink from the pond and we use it to bucket water up to our vegetable garden during dry spells. Just want to make sure its safe.
