I used copper sulfate for algae control in my pond. I ended up killing all my koi. Is there any way to get the copper to dissipate or do I need to drain my pond to reintroduce koi?
Thank you!

Not that I know everything about koi, Andrea, but if the copper sulfate killed them, chances are pretty good it'll kill more of them. Clean your tank and start fresh, would be my advice. However, why not consult a professional? Perhaps someone at the place where you bought the fish and the copper sulfate?
Copper sulfate if not used correctly in right dose then it deoxygenated the water. Best used in smaller amounts
