BIO Wheel

Q. Do I need a BIO-Wheel?

Yes. Biological filtration is critical to the success of any aquarium. If your system has a BIO-Wheel, a culture of ammonia-neutralizing bacteria will grow on its surface. The bacteria will thrive because as the BIO-Wheel provides "wet/dry" biological filtration. As it rotates, the bacteria are nourished by the larger amount of oxygen in the air and water.

Q. My BIO-Wheel isn't turning. What should I do?

If your BIO-Wheel has, in fact, stopped completely, it is probably either because the BIO-Wheel is out of position or because water flow is not strong enough to push the BIO-Wheel.

If water flow is reduced...

  • Unplug your system.
  • Inspect the BIO-Wheel carefully to make sure that there are no obvious obstructions to rotation and that it spins freely when in proper position.
  • Remove the impeller housing and magnetic impeller assembly and make sure the impeller assembly is clear of any obstruction and free to rotate. With a clean cloth or brush, clean the impeller, intake tube and impeller housing.
  • Make sure your aquarium is filled to the bottom edge of the aquarium frame or the level specified in your owners manual.
  • Restart your system. NOTE: If you have a power filter that hangs on the back of the aquarium, be sure to fill the filter box with water.

Q. When should I clean or replace my BIO-Wheel?

Unless it becomes damaged, there is no need to ever replace your BIO-Wheel. A BIO-Wheel actually improves with age. 

Q. My BIO-Wheel is making a lot of splashing noise. Is that normal?

When a BIO-Wheel is new, it has a tendency to rotate more rapidly, which can cause a "lapping" noise. Over time, as the bacteria culture grows, the BIO-Wheel will slow and operate more quietly. (To immediately reduce the sound of water hitting the wheel, grab each end of the wheel simultaneously and gently turn them in opposite directions. This will cause the incoming water to contact one side of the wheel before the other, reducing noise level.)

Had a penguin 75 that stopped working, bought a penguin 100 ( the bio wheel is bigger), where can I put the old bio wheel so it keeps helping with the biological filtration ( since is too small for the new filter)?

Asked by: Vigomateu
Did you try cleaning the impeller and motor of the 75? If this is all it needs, you can run the two filters simultaneously for a couple of weeks. If the 75 is clean but dead, then you can float the bio wheel if it isn't too grungy. BREX

How do you adjust the mid-level strainer? Is that the gray fan-like thing in the middle? Can you give more detail regarding that? There isn't any instructions or details about it in the pamphlet. Thanks!

Asked by: plii
Yes, that would be the mid-level strainer. If you leave it open it increases your flow rate, closing it reduces the flow slightly, and prevents you from pulling water from the middle of the tank. BREX

I purchased the marineland penguin 200 from PetSmart and when I got it home the biowheel was not in the box. Was it supposed to come with the biowheel or do you have to purchase it separately?

Asked by: Melissad
It definitely should come with the bio wheel so please call our Care Team at 1-800-322-1266. BREX

Is there a way to lessen the flow rate so it generates less bubbles? 

Asked by: Plii
The power filter does not generate bubbles, unless the water level in the tank is below the filter's spillway. If so, raise the water level. The only way to adjust the flow is to close the mid-level strainer (gray lever). BREX
