Tetra Whisper Internal Power Filters

It's What's Inside That Counts
The virtually silent submerged motor gives you power filter performance inside your aquarium.

1. Filter pulls water from the tank and pushes it up through the filter cartridge.
2. Dense mesh catches debris and waste.
3. Ultra-activated carbon absorbs odors and discoloration.
4. Bio-foam cultivates aerobic bacteria, which eliminates toxic ammonia and nitrites before water cascades back into aquarium.

As Versatile As It Is Powerful
The Whisper In-tank Filter works in as little as two inches of water, making it ideal for low water level environments like viquariums for turtles, newts, or frogs.

Working Hard Behind the Scenes
Install the Whisper In-tank Filter on the back wall of your tank. Unlike conventional filters, its small size makes it easy to hide with a plant or other decorative object. From the front, it's practically invisible.

The Strong Silent Type

• Full two year warranty.
• Same quality and performance of an external power filter.
• Designed to be discrete for a clear view of your aquarium.
• Space saving--aquarium can be flush to wall.
• Powerful submerged motor has hardly any sound.
• Clean, clear water from efficient three-stage filtration.

Three Filters in One
The Whisper In-tank Filter adjust easily to high or low water levels with mounting suction cups and/or brackets.

• Mechanical Filter
  The Bio-Bag uses dual-sided mesh to catch debris and waste.

• Chemical Filter
  Ultra-activated carbon removes odors and discoloration better than competing cartridges.

• Biological Filter
  Bio-foam creates a large, three-dimensional site for cultivating aerobic bacteria, which eliminates toxic ammonia and nitrites.

Installing the Internal Filter

1. Insert the filter cartridge and foam grid. Note: The front of the foam grid is marked front and should face the front of the internal filter.
2. Hang the internal filter inside the aquarium and press the suction cup against the aquarium glass. Drape wire over the aquarium wall.
3. The lip of the internal filter should be above water level, and the bottom of the internal filter should be at least one inch above the aquarium gravel. When positioning plants and other items, leave about a 1/2 inch clearance around the internal filter.
4. Raise or lower the internal filter by adjusting the filter hanger. Rotate the filter hanger 90°, remove it, and replace it in an alternate alignment hole. In turtle tanks, the bottom of the internal filter should be submerged in at least two inches of water.
5. If the filter hanger does not fit on the aquarium frame, it can be replaced with an extra suction cup (provided). When pressed firmly, the suction cup will fit snugly into the filter.

Danger
Special care should be taken to avoid possible electric shock, since water is employed in the use of aquarium equipment. Do not attempt any repairs by yourself; return the appliance to an authorized service facility for service or discard the appliance.

Warning
To guard against injury, observe basic safety precautions, including the following:

1. If the appliance shows any sign of abnormal water leakage, immediately unplug it from the power source.
2. Carefully examine the appliance after installation. Unplug the appliance if there is water on parts not intended to get wet.
3. Do not operate any appliance if it has a damaged cord or plug, or if it is malfunctioning, or if it has been dropped or damaged in any manner.
4. To avoid getting the appliance plug or receptacle wet, position the aquarium to the side of a wall-mounted outlet in order to prevent water from dripping onto the plug or outlet. Arrange a drip loop for each cord connecting an aquarium appliance to an outlet. The drip loop is the part of the cord below the level of the outlet (or if using an extension cord, below the level of the connector) that prevents water from traveling along the cord and coming in contact with the outlet.
5. If the plug or outlet should get wet, don't unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance. Once the power has been disconnected, unplug the cord and examine it for the presence of water in the outlet.
6. Always unplug the appliance from an outlet when it is not in use. Also unplug it before cleaning, and prior to disconnecting or attaching parts. Never yank the cord to pull the plug from the outlet. Grasp the plug and pull to disconnect.
7. Do not use an appliance for anything other than its intended use. Do not use attachments that are not recommended or sold by the manufacturer; they may cause an unsafe condition.
8. Do not install or store the appliance where it will be exposed to the weather or to temperatures below freezing.
9. Make sure the appliance is securely installed before operating it.
10. If an extension cord is necessary, use a cord with a rating that matches or exceeds the rating of the appliance. A cord rated for fewer amperes or watts than the appliance rating may overheat. Arrange the cord so that it will not trip anybody, and that it will not be pulled in any way.
