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 have the Marineland Bio Wheel Penguin 200 bout it maybe 2 months ago. Wheel stops spinning, water overflows the intake chute. Like the cartidge is stopping the water from flowing. Have taken it all apart and rinsed and cleaned any buildup.

Take it apart again, this time place the impeller into a dish of distilled white vinegar and let it soak for about 15 minutes. Take a paper towel and soak a corner in the vinegar, as well, then twist it and pack it into the motor at the bottom of the filter box. Let it sit for a few minutes, then twist it around to clean out the motor. You may also want to use a small baby bottle brush to clean out the intake tube and the impeller housing. There is some debris somewhere, interfering with the filter. BREX

I have a penguin bio-wheel 200 and the wheel is still spinning but the water is not getting clean, what should i put inside the filter?

Asked by: AwesomeRazor
There are a lot of possible reasons why your tank may not appear clean. It would help to know more about the tank such as how long it has been set up, what kind and quantity of fish, your routine for partial water changes, etc. We would actually recommend a partial water change, addition of Tetra SafeStart Plus, and either a second filter cartridge or adding some additional carbon, ammo chips, floss or bio beads. Test your water quality parameters as well to help determine the issue so you can make an educated guess as to what type of media you need to add more of to the tank. BREX

My filter is brand new , plugged it in and nothing is happening 

Asked by: Ivy1
Pull out the intake tube, impeller housing, and impeller, check them for any damage, then re-seat them. The impeller may be jammed or not seated properly. If the unit still makes no noise, contact us at 1-800-322-1266. BREX

I have a 350 that I bought at least 20 years ago still rocking and rolling. My question is do y'all have reusable cartridges like the company that walmart sells? All i can ever remember seeing are the completely sealed filters.

Asked by: Insaneinnixa
We still have the sealed cartridges, but you can buy media containers for this filter and fill them with whatever type of media you want/need for your tank. Here is a link to a site that carries them. Scroll to the bottom of the list on this page: https://www.petsolutions.com/C/Aquarium-Filter-Cartridges/I/Marineland-Penguin-Filter-Cartridges.aspx?catargetid=520009670000581070&cadevice=c&gclid=Cj0KEQiAw_DEBRChnYiQ_562gsEBEiQA4Lcssvt8NS7mqCrwDs76gaN0PZjLM03QkLXxnQOmy7YseGYaAhpB8P8HAQ.

my 10 Gallon bio wheel filter isn't working. I've tried priming, un plugging it and plugin it back it...... could there be a loose part I should be concerned about?.....or anything else I could do?

Asked by: CFred44
A very dirty filter cartridge can slow the water flow and stop the bio-wheel from spinning. Try replacing the cartridge.

Hi I has a penguin 200 with my 29 gallon tank and the bio wheel has stopped turning and the water started to over flow over the intake tube I put two new filters in on 01/22 and my tank is clear and clean so I think its to soon to need new filters ?

Asked by: Coco
Hi Coco, How often you need to change filter cartridges depends on the size tank, number of fish, types of fish, and feeding routine. Typically, they need changing every two to four weeks. You may also need to clean out the intake tube, impeller, and well down inside the filter box. These areas can build up sludge, algae, and other deposits. Take the filter apart, and clean each piece separately. BREX

Is there any Carbon in the actual bio-wheel? I know the filter inserts have carbon, and I'm not using them intentionally. But something is removing the medication from my quarantine tank and I suspect carbon in the bio wheel.

Asked by: maggarcj
No, there is absolutely NO carbon in the bio wheel. BREX

I have an older bow front, believe 10 or 20 gallon, aquarium that needs a bio wheel, about 2.5 inches in length.  Can you tell me which one I can get.  

Asked by: Susan41
We do not have any that are 2.5" in length. Look on the top of the Penguin filter to see which model filter you own. This will tell you what bio wheel you need as well. The model number is molded into the cover, in one of the corners, depending on the model and the age of the filter. BREX
