Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants eat fish from copper treated pond?

every year I have fil. algea and I treat it with copper sulfate and it seams to do the trick...this year I stocked the pond for the first time.

from what I read, I should be fairly safe from killing fish since most fish kills occur due to lack of O2. Am i correct on this?

and would you eat fish from a pond treated with copper sulfate?

3/4 acre pond. owned pond three years. major duckweed/water meal problem with no fish population. dumped in floridone. added aerator with two air stations installed two years ago. stocked with BG,HBG,LMB,Catfish,Redear. all pretty small.


thanks
