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.)

If I have a 38 gallon fresh water tank would the bio wheel 350 be to big of a filter for it? 

Asked by: Mhhh
No, it would not. I have a 38 gallon and have run that filter, along with the Penguin 200 simultaneously, without an issue. I keep small fish such as tetras, typically, live plants, angelfish, etc. BREX

Has the Marineland 350 changed from up 75 to 70 gallon. I just purchased a new one a couple of days ago and the one I received says up to 75 gallon tank. I have seen them on different websites advertised as 70 gallon. What is the differents ? 

Asked by: zippy man
The new packaging states they are rated for up to 75 gallons now. New research verified the higher flow rate on this product, so we changed the packaging. BREX

HI. My biowheel has white fuzzy mold or something no growing on the edges. is this healthy?? There's black fuzzy too. It's been set up 5 years and never had this.

Asked by: Ashleyzappe
Could be a type of algae most likely. Just remove the bio wheel and using a q tip, clean between the folds. Also, take the filter apart, and clean each piece individually as well. BREX

I've got a deluxe mag350 that came with a biowheels but I cant find the attachment to it from the hose outtake. Where can I get this part?

Asked by: happypoon
If you are referring to connecting the outlet to the bio wheels, the only parts we have left for the Magnum Pro filter are these: http://www.marineland.com/search.aspx?q=bio%20wheel%20pro#/?filter.brand=Marineland. BREX

Does the bio wheel spin at a rapid spin or just slow and spin

Asked by: jackie01
When you first install the filter, it will spin pretty rapidly. Once it absorbs water, it will begin slowing down, and once it builds up a really good bio load, it may actually start and stop. There is no right or wrong speed. Slower is generally better just because the bio wheel is exposed to oxygen for longer periods of time, leading to more biological filtration. BREX

Hi, my Marineland Penguin bio wheel 75 has not worked. It has been off and on, and my 4 year old fish are at risk. They are rare fish. Anyway, any suggestions on how to get it working? Tried starting again, unplugging, cleaning it. PLEASE help. Thx.

Asked by: JacieBoo
If it is starting and stopping so to speak, make sure you do not have sand in the aquarium that could be causing the issue. When sand is in use, you need to place filter floss inside the strainer or put an accessory sponge over the strainer. Another thing that will cause filters to turn on and off are air bubbles. If you have an air stone in the tank, try turning it off and testing the filter. Take the filter apart, removing the intake tube, impeller housing, and impeller. Clean it thoroughly, especially the impeller, and the bottom of the filter box, where the impeller resides in the motor well. You may have some sludge or other build up causing an issue. In the event of hard water or marine water, use distilled white vinegar to clean everything and rinse well. Last, make sure it is plugged into a power strip and not an outlet in case of voltage issues, if this is an older home. A filter's purpose is not to keep the fish alive, but to reduce the maintenance of the tank. So until you determine what the issue is with the filter, step up on the water changes. Vacuum and do 10% at a time, every couple of days, if the filter continues to have an issue. Also, call us directly so we may assist you. 1-800-322-1266. BREX

I'm building a 10gal nano tank with red crystal shrimp and vary tiny rare fish is the penguin power filter 100 safe for fry and baby shrimp or will they be sucked into the filter and if so is there a way to put a protector sponge on the filter intake

Asked by: Arux584
The only type of filter that would be safe for fry and baby shrimp would be a sponge filter, operated by an air pump. If you use the Penguin filter, place filter floss inside the strainers. This comes in bags for just a few dollars and looks like a giant cotton ball. BREX
