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 am setting up my 5.5 gallon tank and bought the bio wheel 100. If I attach the mid-level intake strainer, and the Extension tube, it is too long and doesn't fit my tank. Can I just add the strainer to the intake tube?

Asked by: Nikki T
Yes, correct, you do not use the two middle pieces, just the intake tube and the bottom strainer.BREX

I just purchased a Penguin 200 yesterday. Primed and plugged, filter started no problem. Woke up this morning and filter was seemingly dead. No noise, no water flow. Unpluged filter, removed impeller no apparent debris. Reinstalled still dead.

If you are not feeling any vibration at all or hearing even a little bit of a hum when you install the impeller, then it does sound like the motor may not be working. You may want to try a different outlet, in the event that you have not already done so. Otherwise, please call 1-800-322-1266 for further assistance.BREX

I buy a marineland bio-wheel led kit 2 weeks ago and the filter doesn't work. The wheel just stop spinning.What can I do to get work my filter?

Asked by: Kaveza
There are a number of possible reasons for this issue. Make sure the tank is filled with water to just under the top black frame. Remove the intake tube, impeller housing, and impeller. Clean all three of them well. Re-insert them into the filter system. Once water starts flowing again, give the bio wheel several seconds to start turning. You may also want to check your cartridge, pull it out and re-insert it. Remove the bio wheel, check that there isn't anything caught in it or that there is anything on the spillway interfering with it. If you continue to have issues, please call 1-800-526-0650.BREX

model 350 water is over flowing over and around the fiter

Asked by: Jennypeters
That is a sign that you have a clogged filter system that requires cleaning. Remove the filter and completely take it apart, removing all media, the intake tube, impeller housing, and impeller assembly. Clean the parts well with hot water and white vinegar, then re-install everything and place the filter back into use.For further assistance, call 1-800-322-1266.BREX

Will the intake tube from a 350 fit a 200 as an extension? I need to make my tube longer but can not find one for the 200 but I can find the 350. Plz help.

Asked by: Beaver
Good morning,Thank you for your inquiry. The extension tube for the Penguin 350 and Penguin 200 are the same and therefore can be used interchangably.MINI

I have an established 10G with Penguin 75, with 5 Neon Tetras. I plan to add 4 Pygmy Cory and 1 Dwarf Gourami. Will my current filter suffice?If not should i upgrade to penguin 100 and how do i go about this?

Asked by: Prakash257
Good morning,Thank you for your inquiry. Yes, this filter is more than appropriate for your tank. Please make sure that you are monitoring the feeding and don't overfeed and are performing water changes at least once a month 30% of the water level in your tank to maintain a healthy aquarium.MINI
