Buzzing is usually a voltage issue. This means there may be low voltage in your neighborhood. That is common when temps are extreme and everyone's heat is really cranking it out. If the filter is plugged into a power strip with surge protection, that usually eliminates the noise. Another possibility could be build up, sludge, hard water deposits, other debris on the impeller or in the motor. Taking it apart and cleaning it may resolve the issue.

The last possible cause would be an improperly balanced impeller. If you take it apart and give it a good cleaning with white vinegar, and have a good power strip, and it still buzzes, call our Care Team at 1-800-526-0650. The unit has a 2 year warranty with receipt.

Description Ensure your Tetra Whisper Aquarium has the quiet, reliable filtration it needs with the Whisper Power Filter. This easy-to-use system introduces your tank to three stages of filtration—mechanical, chemical and biological—to completely eliminate toxic ammonia and nitrites for a crystal clear aquarium. Its water flow was scientifically engineered to create a continuous flushing action, which can help prevent debris buildup and keep your tank cleaner than ever. Key Benefits • For a crystal clear aquarium, this filter completely eliminates toxic ammonia and nitrites. • Economical and easy to use, even for beginning aquarists. • Provides efficient three-stage filtration—mechanical, chemical and biological. • The scientifically engineered water flow provides a continuous flushing action to prevent debris buildup.

• Optimum outflow maximizes water agitation and oxygenation. Filter not included. Keep your system running smoothly. Changing the Bio-Bag®: When water flows excessively from the Wonder Tube Chamber into the aquarium, it is time to change the Bio-Bag®. The Bio-Bag® should be changed once per month to prevent backflow and avoid filtration problems resulting from a clogged Bio-Bag®. Using a ready-to-use, assembled Bio-Bag® • Remove filter box cover. • Lift Bio-Bag® and allow excess water to drain into filter box.

• Dispose in garbage can. • Rinse new Bio-Bag®, insert into filter, replace filter cover.

Using an unassembled Bio-Bag® • Remove Bio-Bag® from filter, allowing excess water to drain into filter box. • Remove clip from frame, fold up frame flap, and remove floss bag from frame.

Place new floss bag over frame. • Add one packet of Ultra-activated® carbon. • Fold flaps of Aerobic Frame® over filter bag and replace clip.

• Rinse Bio-Bag®, insert into filter, replace filter cover. Maintaining the Energizer: Caution: Only remove Energizer when absolutely necessary. • Unplug power cord, empty filter box, and place it upside down on a flat surface. • Grasp Energizer with one hand and filter box with the other.
