I took the COR20 out of my tank over the weekend to give it a cleaning, when I pulled the impeller it looks like there is a rust spot? I did contact support to get clarification, wanted to see if anyone else has experienced this?

I have seen similar marks on other pumps. My guess is it is some type of contamination that rusted when it came in contact with salt water. I would not be overly concerned with such a small mark. What did the impeller assembly look like?
