    COR 20 Rust?

    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?

    The internal parts of the pump look just fine! I should have taken some pictures of it when I pulled it out.
