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.) 

I recently bought marineland 20G tank comes with penguin power filter, after a week running the filter I started to notice significant amount of micro bubbles all over my tank. Is this due to the filter?

Asked by: sarors
Most likely it is due to a low water level in the tank. The water level should be to the bottom of the top frame, otherwise, water spilling down from any filter will create more bubbles. BREX

I purchased a Marineland tank from someone. The person I purchased the tank from said her fish passed due to an illness. I am concerned whatever made her fish ill may have infected the bio. Should I replace it before introducing my fish to this tank?

Asked by: vNocturnalAngelv
No, you do not need to replace the bio wheel. As it has presumably dried out, whatever disease was present is no more. BREX

I purchased my Marineland tank from someone without a box or instructions. It seems to be about a four gallon tank, bowed front and a hinged hood with filter and light. I looked on the outside for a model number but couldn't find one. Any insight?

Asked by: vNocturnalAngelv
We would need to see a picture of it to be sure what it is, but it could be a Pillar or an Eclipse. BREX

Can the penguin power filters be run without the carbon? I would like to use the filter for a saltwater QT tank and do not want to use carbon filtration in case I need to medicate a fish/coral.

Asked by: Dale64
Yes, it can be operated with other media if you prefer, as long as you do not overfill it. BREX

I bought a 350 through Amazon and have had it running about 4 weeks and the power went out. It has not worked well when the power came back on. I removed the impeller and it seems to turn free and easy. It does not work at all now. Very disappointed. Help

Asked by: Headbum
If you are not hearing any noise at all, not even some vibration, the motor was probably damaged during a power surge. If it is still making noise, has vibration or magnetic pull, clean both the impeller and the well of the motor with white vinegar, very thoroughly, and rinse well. If you cannot resolve this issue, please call us at 1-800-322-1266. BREX

My bio wheels are squeaking when they rotate; is this typical and is there a solution to stop the squeaking? Thank you for any help! 

Asked by: SullivanL
I think my wheels were squeaking due to the tank not being level; the wheels slowly move to the right side of the filter. The plastic side of the wheel rubs against the side of the wheel housing making the squeaking noise. I plan to perfectly level the tank which should solve the problem.
