Marineland Penguin Bio Wheel Assembly Replacement for the NEW Penguin 100B Power Filter. Note that the Bio-Wheel should only be replaced if damaged. Discoloration of the pleats is normal and indicated proper functionality. The Bio-Wheel spinning at any speed is still working to eliminate ammonia and nitrate, and irregular rotation is normal.

The original box said these bio wheels don't need to be replaced; just rinse and reinstall. Ours was slightly crushed and never quite worked right. I was happy to find Pet Mountain carried the exact part I needed.
Great product. Does the job!
