product highlights

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.

Rated 5 out of 5 by from Pefect fit Normally you don't have to replace these, but since I purchased a used filter, I was missing the bio-wheels. Works great, last long time!

Rated 5 out of 5 by from These wheels are a good solid product. Any issue I have had with marine land has been handled easily by their customer service team. The wheels are great, but the system running these wheels is not great.

Rated 5 out of 5 by from It takes care of all the ammonia & nitrates that are harmful to the fish. Low maintenance with little or no cleaning at all.I have the 350 Penguin power filter.A great product thus resulting in little or no testing at all.It does not however control the PH level.That is done with a separate test kit.

Rated 4 out of 5 by from Works great! I know you aren't supposed to replace a BioWheel unless it gets damaged... My turtles took the cover off my filter and pulled out my old wheel a couple of times- it was even submerged in their water for a few hours and mostly unraveled. I got a new wheel and was pleased with the shipping time, but the quality seemed like it could have been slightly better. The wheel doesn't stay centered on the axle, and the mesh accordion covering was coming away from the frame, similar to the way my old one was. It does fit in my filter though an is functioning as it should- my water looks wonderfully clear again.

Rated 2 out of 5 by from fast shipping that was it I put the bio-wheel in my tank and it does not even spin, I wish I did not spend the ridiculous amount for 2 of them for my filter. I could of almost purchased a new filter for what the wheels cost.

I bought a new emperor filter and I was changing out the filter pads and I noticed that one of the wheels had a small tear in it. It is not spinning as fast as the other one. Do I need to replace it? If yes with which one?

Asked by: AJ nm
Not necessarily, AJ, but certainly if the filter is new, we want you to get a fully working one in excellent condition, so call 1-800-322-1266 and request the bio wheel be replaced for you. The Care Team will need your receipt, full name, address, and phone number.

My current wheel will not turn. Does this mean I need to replace it?

Asked by: JPUJR
The plastic pieces did not fit. Switching sides of the wheel made it start turning.

BIowheel on Penguin 200 only rotates when the pump is tilted about a half inch. Its been like this since it was new. It is very unattractive. When level the biowheel never turns and one side dries out. What can I do?

Asked by: Geralyn
The bio wheel is dependent on the flow rate of the water, so make sure the water level in the tank is correctly at the top of the tank. Also, take out the impeller and clean it as well as the bottom of the filter box. And finally, the bio wheel should rest in purple tabs called bearings. Make sure they are properly in place, clean, and have a thin smear of silicone lubricant on them.
