I doubt it was the tetra filter most impeller magnets are ceramic. Im pretty sure the frag rack magnets are nickel and copper.
Or is it rust from the frag rack that stuck to the impeller? Had a similar thing happen to me with a tunze magnet but when I cleaned it off the magnet looked perfect. I realized the gfo particles were atteacted to the magnet making it look rusted.
The problem with steel rusting is it is not just iron, most have allot of impurities in it and I believe sometimes that impurity is copper. Allot of heavy metals are bad for a reef.
Iron is used up in a reef tank though sometimes.
Rust has always been thought to be bad.
Randy may know more about the difference between rust and iron.
I know there has been lots and lots of post over the years where people believe rust was a issue with their tanks. Rust has always thought to have been bad.
Remove the rusted part add some polyfilters and see if things clear up.
There was a issue a while back where pumps from China were rusting. Basically most underwater pumps are sealed in epoxy and they were not fully encapsulating the motors in epoxy.
Thread started with one guy who could not figure out what was wrong and one day he grabbed the pump and all this brown stuff pored out. Aall of a sudden there were allot of people who had the same problem with the same pump.
Were the Pumps Jeboa?
I have one of them now which is why I'm in the market for a new external skimmerNope they were pumps used in some major brand of protein skimmers.

Just inspected my waveline dc 10000 and discovered the impeller rusted really bad the coating appears to have failed on the pump itself and it's rusted totally! Corals looking bad attribute it to Rust! Tank 200 gal has been on line flawless with no problem until now. Please if anyone else has had this issue with the waveline pumps please speak up as don't want to use this pump if it has issues with rust!I know someone who couldn't keep any corals alive in his tank. Turns out he had a rusted hose clamp submerged in his sump. I also have heard of corals looking bad if you have a rusted impeller (sump/skimmer pumps don't get cleaned/inspected as often.)
Google magnets reef2reef. There a few good articles.Waveline dc pump impeller housing falling apart rusted like Crazy! Anybody else with waveline dc pumps experiencing the same issue. Reef suffering think I found the Problem? Any imput will be appreciated. Red rusty water impeller almost rusted in place when went to clean. Doubt the pump would have run much longer! No telling what contamination I have to deal with!
Reread the thread here.Hmmm! Wonder what the metal content in the water rises to in a closed system like most all are and would be it be detrimental to reef health!
