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.) 

Hi... I have a penguin with the two bio wheels. I cleaned out and emptied the tank to sell.. but after a few months decided to keep the tank. Should I buy new biowheels or am I ok to continue with the ones I have even though they have been dry for a bit?

You can definitely use the old ones as long as they are not damaged or warped. They will build a bio load again after a few week, as if they were brand new. BREX

How wide does the tank cover opening need to be for the 100 or the 150?

Asked by: DrewM
The 100 needs 5.5" in length and at least 2" in width. The 150 needs 8" in length, and close to 3" for the width. BREX

I just picked up a Marineland Bio-Wheel Penguin Power Filter, Size 200 and I was wondering if there was a way to adjust the water flow? I want to slow the flow down

Asked by: Steve519
You can close off the mid-level strainer, and this will effect the flow somewhat, but not a lot. BREX

My Bio-Wheel is not turning and I followed every step and instructions you mentioned.

Asked by: ABUELA
Then at that point, you call in to talk to a technician to make sure you've done everything possible and done it correctly. If so, you may have warranty if you have your receipt as these filters have a 3 year warranty. BREX

Asked by: jay s
Hello, jay s! We're sorry to hear the motor is noisy. That indicates an issue with the impeller. We suggest turning the filter off, removing the intake tube then cleaning the impeller and impeller well. For troubleshooting help please call Marineland at 1-800-322-1266.

I bought a new bio wheel penguin 200 power filter today to replace a loud top fin filter, it worked for a little then I unplugged it as I was putting sand in my tank. Then I plugged it back in it made a sound and will not work. Please help 

Asked by: Raepets
We're sorry your filter isn't working, Raepets! We suggest turning off the filter, removing the intake tube and inspecting the impeller well. It is likely that sand got into the filter clogging it up. For help call Marineland at 1-800-322-1266. We are happy to help!

I have a 40 gallon turtle tank, that opens half way so that the filter is resting halfway also. Would any of your filters fit a tank that opens halfway? About 9 inches of water.

Asked by: julieb63
Thanks for asking, julieb63. The hang on back filters are meant to be used with a completely filled tank. For a turtle tank set-up like you described you may wanted to consider a Magniflow Canister filter. For personalized product suggestions please call Marineland at 1-800-322-1266.

What is the replacement filter for what was included with the 5 gallon escape kit? Thanks!

Asked by: Unhappy fish
That tank takes Rite Size Z replacement cartridge. The filter system is not sold separately, you would simply remove the intake tube and impeller housing to open the pump. This allows you to take out the impeller and clean it and the pump to keep it running. BREX
