Replacement Replacement Bio-Wheel for Eclipse 2, Emperor 280B & 400B Filters. Marineland Bio-Wheel should not be replaced unless damaged.
Marineland Bio-Wheel should not be replaced unless damaged.
The water flow from your filter drives the Bio-Wheel. As the Bio-Wheel rotates, beneficial bacteria grow and thrive on its super dense surface. As water flows, the Bio-Wheel eliminates ammonia and nitrite on
contact.
- Irregular rotation of the Bio-Wheel is also normal
- Discoloration of pleated Bio-Wheel material is normal and desirable
- A Bio-Wheel rotating at any speed is working to eliminate toxic ammonia and nitrite
