Editorial Review The Marineland Bio-Wheel Assembly Replacement is designed to work with the Emperor and Eclipse 2 Filters. The Marineland Bio-Wheel should only be replaced if damaged. The water flow from your filter causes the Bio-Wheel to rotate which helps beneficial bacteria grow and thrive. As water flows, the Bio-Wheel works to eliminates ammonia and nitrite.
Features 1) BIO-Wheel Emperor Assemblies for models PF280B, PF280BD, PF400B, PF400BD, and PFE2. 2) Replacement of this part should only be done if the bio-wheel will no longer spin or if the wheel is broken or damaged. 3) Discoloration of the pleated Bio-Wheel material is normal and desirable. 4) A slight irregularity in the Bio-Wheels rotation is normal. 5) Rotating at any speed the wheel is working to eliminate toxic ammonia and nitrite.
