When I ran an ASM skimmer, the Sedra pump it ran on, seemed to be prone to the impeller magnet starting to bulge out over time, and it would have trouble starting after a while. Had to replace the impeller altogether. The bulging was very subtle, at first I didn't believe that was the cause, but it was. New impeller, pump had no trouble. Think I only got around 18 months per impeller replacement.
