I am the president of a 22 acre lake in upstate SC. The last 2 years southern naiad has appeared around Memorial day and taken over our lake/pond. I have spoken with the local Clemson agriculture officer and they recommended using a copper sulfate additive to be administered by a professional pond management company. In addition to this we had a pond pro out to talk about dumping some lime in the lake as the ph is a little low. He said to just continue adding grass carp (we added 300 back in the spring) to handle the problem until they caught up.

Now I am asking you guys, who is right here? I know the copper sulfate additive will work but its 5-6K to do that and there is no guarantee that the naiad will not come back.
