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 a eclipse 1 wet-dry filter system my question is can I replace the impeller of a different size in order to get a better flow across filter media and bio-wheel?

No, the impellers are system specific. BREX

Got a new 350 filter and with in 3 months, it started making noise and doesn't pump water continuously. It stops pumping in between so frequently. Any idea ?

Asked by: Bharath
It most likely has some debris caught somewhere. Remove it from the tank, take out the intake tube, impeller housing, and impeller, and clean each part. Also clean out the well of the motor in the bottom of the filter box. BREX

My filtration system lessens pretty rapidly due to slimy algae buildup in the tube and impeller. I have to clean it out about once a month. The bio wheel stops turning and develops a white crust. Probably minerals. Is this detrimental to the bio wheel?

Asked by: Tdavis4
Sounds like you need some help with the tank in general. Yes, if it is not spinning, it can be a problem for the bio wheel as a lot of the bacteria could die off, if left out in the air to just dry up. Are you doing monthly water changes? The white crust sounds like hard water or it could be a water mold. We would recommend either switching to bottled natural spring water if the tank is small, or if larger, then you might want to invest in a purifier for the faucet or a RO unit. If so, have a supplement to add minerals/trace elements back into the water when you do water changes. Another option would be adding peat to the filter or a water softener pillow. We could be more specific in our help if we had more info on the tank. BREX

I would like to construct a lift tube extension for my Penguin 100 filter (This is the round lift tube, like the old 75, not the rectangular style). What tubing dimensions will I need to slip-over the OEM lift tube?

Asked by: DudleySockpuppet
We have not made a round intake tube in 20+ years and do not have specs for such. The Penguin 100 has always had a square tube, but our old Mini and 99 had rounded ones. We recommend taking the intake tube with you to a DIY hardware store and matching up the tubing with it. BREX

 I found two buckets of fish and an aquarium in the parking lot. The penguin water thingy doesn't make any noise when plugged in.  Where's the fuse? It's big, has two filters that rotate. 

Asked by: one666mom
Wow, poor fish! Pull the intake tube up and out of the filter body, then reach in and pull up the piece the tube came out of, the impeller housing. You may need to clean out the entire filter system. If you see hard water deposits, use white vinegar. Instructions for the Penguin 350, which you have, are on our site: http://www.marineland.com/Products/aquarium-filters-and-protein-skimmers/penguin-bio-wheel-filter-saltwater-filter-freshwater-filter.aspx BREX
