Don’t panic. Chances are, the wheel is not permanently
stopped. Irregular rotation, including brief pauses, is normal.
As long as the wheel continues to move periodically and
remains wet, it is functioning properly.
Inspect
BIO-Wheel Bearings and Axle for dirt or mineral
deposits. If evident, clean these areas carefully.
Make sure
all parts are installed properly and that there are
no obvious obstructions to free rotation.
Check
Spray Bar and Spray Bar apertures for obstructions.
If evident,clean areas carefully.
Examine
Intake Tube for flow obstruction.
Perform
regular filter maintenance.
This is not a problem.
It indicates the development of beneficial
biological culture.Do not attempt to clean BIO-Wheel pleats.

Be Sure
you have primed the filter box properly (fill box
1
/

full
prior to plugging in system) and that Flow Control is in the
“full flow”position.
Make certain
the outlet has power and is functioning
properly by first unplugging electrical cord momentarily,
then reconnecting to power source to restart the Impeller.
Check
to see that Flow Manifold is seated firmly in Filter Box
and that aquarium water is at correct level (
1
/
2
”-
3
/
4
”from top of
aquarium).Inspect Intake Tube to ensure that it is not displaced
from inside the Impeller Housing Collar.
Remove
Flow Manifold and make certain that the Magnetic
Impeller Assembly is free to rotate. A particle of carbon or
gravel may be interfering with rotation.
Remove
Flow Manifold and make certain Magnetic Impeller
Assembly is free to rotate. Debris may be hindering silent
rotation.
Replace
worn or damaged Magnetic Impeller Assembly.
Refer to parts list for part number.
Allow 24-48 hours for “breaking in” period. Material in
a BIO-Wheel is not fully absorptive when new.
Check aquarium water level. Lower than normal levels can
result in excessive splash or noise.
Adjust Spray Bar to ensure slow BIO-Wheel rotation.
