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.) 

My power went out now my 350 will not propel water over the edge it makes a rattling noise. It does that when its about to go over normally but now it stops pushing the water thru

This is a sign it needs to be taken apart and cleaned. Pay close attention to the impeller and the bottom of the motor, where the impeller resides. If you are unable to get it operating, call 1-800-322-1266. BREX

my biowheel 200(13 weeks) on my saltwater tank (37 gallons), has stopped completely and wont work , theres no water damage ive done only filter change and tube cleaning ,, I need this filter to work , I set up temp diy one with your maxijet 900 and a 2l

As it is a marine tank, you need to remove your impeller and impeller housing every month and soak the impeller in distilled white vinegar to keep it free of salt crud. Also, clean out the well of the motor by soaking a paper towel and packing it into the motor for a few moments, then twisting it around, and pulling it out. Rinse everything very well with hot water.

I took my 350 filter apart and cleaned. Since I have reinstalled one of the bio wheels is flying fast and the other is normal. Water speed is much faster on this side. I have adjusted intake. Please advise.

Asked by: twelcker
That's not an issue, but apparently you either have something partially blogging the filter on the slower side or the bio wheel is damaged or clogged. To clean a bio wheel, take it out, and use a plain q tip with out any chemicals or detergents, and swab between the folds. BREX

We just got a penguin 150 to use for a turtle tank but we can't have the tank that full of water will this work for us or not

Asked by: Lee t
The tank should be 3/4 of the way full for an aquatic turtle, and this will not be high enough for this filter, so no, it would not work for you. We would recommend the Magniflow 160 instead. BREX

What is the mid-level intake on the filter tube for? In what position should the lever be in? Does it make any difference?

Asked by: thecaptain
It increases and decrease the flow rate. Open increases it, closed decreases it. I leave it open all the time in my tanks, but it depends on your tank, and its needs. BREX

Which way is the lever on the filter tube supposed to be? Up, down or in the middle for ultimate suction? Lost the instructions.

Asked by: BobT
That is personal preference. It increases the flow rate when open, and decreases it when closed. I simply remove mine so it is fully open all the time, some people close it when feeding. Every tank and tank owner has different needs, there is no right or wrong. Instructions are available on the product page on our site. BREX

I have 2 Fish Tanks. 1 is a 5 Gallon and the other a 10 Gallon. The smaller 5 Gallon tanks filter cartridge was a rusty red color. What is that and is it dangerous ? Even after rinsing it under sink water it's still kinda red.

Asked by: Jay1973
Could mean you have iron in the water, but I would expect both tank filters to appear red. So it may be that you are over feeding the 5 gallon tank. Feed one piece of food per inch of fish, twice a day. Another possibility, but not likely is cyanobacteria. That usually grows throughout the tank though. BREX
