This MARINELAND Penguin 200B/350B Bio Wheel Assembly is a sturdy and dependable replacement part for Penguin Filters. Do not replace a Bio-Wheel unless it is damaged since beneficial bacteria live on it. Discoloration of pleated Bio-Wheel material is normal and desirable. Irregular rotation is also normal. A Bio-Wheel rotating at any speed is working to eliminate toxic ammonia and nitrite.
