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 looking for the bar/piece that holds the actual Bio Wheel for a Penguin 125. Got any ideas? Thanks, Scott

That would be the bracket, and it is not available, unfortunately, since that filter has been out of production for over 15 years. BREX

I have a 10 gal tank and the intake tube is to long, do we need to have the mid level intake installed or can we just use the end piece. The tank is being set for an axolotl.

Asked by: Jay611
You would use just the bottom strainer and intake tube, no middle pieces, as those are in case someone has a 20 gallon tank. BREX

I have two Penguin Biowheel 150's in my 36-gallon bowfront tank. Is that too much? Right now, I have a small fancy goldfish and he seems to get "caught" in the current alot.

Asked by: LakeSuperior
No, that should be fine, especially when he gets bigger. Put some tall plants in front of the filter intake tube to break up the flow for him. Also, test the water and make sure it's okay and he isn't stressed. BREX

I purchased the bio-wheel 150 filtration system 5/21/18. I still can not get the bio-wheel to spin. i have soaked it water overnight and used petroleum jelly to lubricate the brackets. I think something is wrong with the wheel it self. It will not spin.

Make sure the water level is to the top of the tank. If it is, then call 1-800-322-1266 to talk to our Care Team about a replacement bio wheel. BREX

My biowheel won't turn. I returned one filter to Petsmart because the biowheel wouldn't turn, and the one on this new one wont' turn either. I have taken it out an checked for damage, I have gone online and done all the suggestions that were blogged.

Asked by: GrammyKimB
Where is the water level in the tank? Check the bio wheel bearings. If they are in place correctly, put a thin smear of petroleum jelly on them. Call 1-800-322-1266 if you need more help. BREX

Do I need the mid level intake strainer because with everything attach strainer will be digging into the gravel which make the filter fit improper I have 10 g with the penguin 100 filter

Asked by: Tyy420
Nope, you sure don't! In fact, it is included in case someone has a 20 high. You just use the intake tube with the bottom strainer for a 10 gallon tank, with no middle pieces at all. BREX

My Marineland 350 Penguin Power Filter just suddenly stopped workin. The day I added in PH-raising substrate, so now my tank is extremely dusty. The filter came with the marineland 55 gallon kit, is there any way some sort of warranty covers this?

Asked by: RanusH
Have you tried cleaning it out? In most cases, it just needs to have the impeller, impeller housing, and intake tube removed and cleaned. You also need to clean out the motor. I would guess that the pH powder clogged the impeller and caused it to stop turning. Warranty is 3 years on manufacturing defects, you would need to call 1-800-322-1266 for the address, and other information. Receipt would be necessary as well. BREX

I am considering buying a Marineland penguin 350 C for a live well I am building.  It will require a longer intake tube to work.  Can you tell me the parts I need to do that?  Also, if I extend it twice, will the pump handle it?

Asked by: Mike7631
You would need a mid-level strainer and an extension to lengthen it. It will be fine with one additional one of each of these, but may not be powerful enough for two additional extensions. BREX
