This year is the first year my pond was taken over with algae. Not sure if the aerators made it worse or what. I treated with a little copper sulfate which may end up being a disaster, the water went from clear to a murky green and I'm worried I may start losing some fish. I saw a couple perch floating, hopefully it doesn't get worse:mad: Jeff is there a safe way to treat algae without having the results I did, maybe Cutrine Plus? I also think it would possibly be beneficial to add a bunch of crayfish.
