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.) 

Does the Penguin filter range run off 220Vac also, or only designed for 110Vac?

Asked by: ianrwood
It is designed for 110V only. You could use a converter perhaps. BREX

I am upgrading from a10 gallon aquarium kit to a 37 gallon marineland tank and stand the new tank does not come with a filter. Can In use the penguin from the marineland 10 gallon kit and add a second filter?

Asked by: Jrc55011
You can use it, yes, but it won't filter much. It's main purpose will be to help seed the new tank with good bacteria. Other than that, there really isn't much point to use such a small filter on that size tank. I would run it for a week or two while the tank is cycling, then remove it. You need something like a Penguin 200 for proper filtration. BREX

Hey , I cleaned my bio wheel and tank now it is running loud. Can anyone help m out?

Asked by: Butcher
Well, when you cleaned it did you remove the impeller from the bottom of the filter box? Noise typically comes from something being caught in the impeller or motor region. It can also occur if the intake tube is not seated correctly or if there is an air stone near the intake tube. Sand getting caught in the impeller will cause grinding noises. So basically, it is always a good idea to remove the intake tube, impeller housing and impeller, inspect and if necessary, clean them. Also inspect the motor region as well. BREX

For a 30 gallon aquarium is a Penguin 150 or 200 advisable? I don’t want to potentially get a strong one that will be splatter water all over.

Asked by: Karim117
That depends on the tank's needs, basically. The Penguin 150 is rated for tanks up to 30 gallons so you would be maxing that filter out, depending on the type of fish you are keeping. The Penguin 200 is not overkill and is often used in that size tank, especially for goldfish and cichlids which are particularly dirty fish. Neither filter will splatter water any more than any other filter, but we do recommend floating the biowheel for the first day or so to help it to absorb water and eliminate noise in new filter systems.

Bio doesn't spin. Water flows back next to the intake tube. Water level is high enough. What's the problem?

Asked by: Scotteh
Same with mine. No obstructions, water is high enough in box and in tank, everything is good but it doesn't want to spin.

I have a 150 and a 350 the 150 seems to be moving a lot more water than 350 what do you think the problem might be the 350 is brand new

Asked by: mumblypeg
Well, since the motor and the impeller on the 350 is much larger, that certainly isn't possible. Also, the flow is split between two chambers so keep that in mind. Some possible causes can be clogged cartridges, low water level in the tank, or if you added additional media, this would slow it down too. Also, even with a brand new filter you can pull something into it that may interfere with the impeller. Check it for plant matter, sand, grit, carbon dust, and so forth. BREX

Hi i love live in Barbados and I have the filter but there are no cartridges available what can I do since there is none. Another question is that my water in the tank still isn't keeping clear what might be the problem i have 150 filter

Asked by: Trinity27
As we do not export our products, we cannot advise on how to purchase our products outside the U.S. In regards to the cloudy water, that could be due to any number of possible causes. New Tank Syndrome, adding fish too fast, too many fish for the tank, over feeding, microscopic animals such as heterotrophic bacteria, water changes not frequent enough or too frequent, and so forth. Without any information on your tank, we would recommend testing the water quality, vacuuming the gravel and changing out 25% of the water. We would also recommend adding a bacterial supplement like our Bio Spira. BREX

I purchased a 200 model for my 50 gal tank does it matter that the intake pipe only goes 2/3 rds of the depth or the water?

Asked by: Jsmall
No, not at all. Anywhere between 1/2 and 3/4 of the way down is recommended. BREX
