I had a piece of stainless that was part of a Sicce pump I picked up that was starting to show some rust. For about a week my skimmer was going nuts and I could not figure it out I did 3 big water changes and it didn't help. I finally noticed the piece of metal and removed it. 3-4 days later the skimmer went back to normal. Not sure what it was. Could it have been the rust?
