I've own pond 2 years. 1.2acres with 3 springs that kick off, I would just guess 25GPM+ I have used copper sulfate but reading more about the cons. I do notice a non-appeal brown green color to pond after a week or so after treatment. And, algae bounce back. Super clear water so tried dying blue to help. With the spring, the blue had washed out in less than week.

Looking at aerating. Obviously i would place at the end of pond by spring, away from spillover. Grass carp and what I’ve done so far just isn’t cutting it. if i just fished the pond, i wouldn’t care as much, but wife wants to feel better about swimming.

So, question is, with that much flow, is it a waste or just do it and see? I don’t mind spending 300-500 bucks if it meant i didn’t have to fight it anymore.
