Correct. It is important to keep the axles and axle-ways clean and
free of debris. It is normal for an established bio-wheel to 'hitch'
or stop on occasion, but if it stops long enough for the pleated
fabric to start drying, you have a problem. I prefer the filters with
a spray bar that is directed at the wheel to keep it rolling. Even
with the wheel loaded up with 2 years worth of gorp and slime, as
long as I keep the axles clear, it never stops.


What is the brand? How big are they. I foolishly positioned my 75
gallon tank too close to the wall and have a tight fit with the
Penguin 330s. I think it is about 4 inches of room to the wall.
