• When medicating fish, remove the carbon from the Bio-Bag
carbon adsorbs most medications.
• To service the impeller yearly, or if the motor is noisy, unplug the filter and remove it from the aquarium.
Remove the motor (see Illustration A), open its cover, and flush debris with clean water. Soak the impeller in
distilled white vinegar using a cotton swab to wipe debris, and rinse. Replace the motor in the filter and install it
in the aquarium using the instructions in this manual.
• It takes a few weeks for new aquarium water to cycle. "Cycling" a fish tank means growing healthy bacteria
on a new filtration system so it filters out dangerous toxins. Tetra
aquarium immediately so you can add fish right away.
1. Attach the filter hanger to the track on the back of the filter
by aligning the water drops as shown (Fig. 1).
2. Clip the filter to the back wall of your aquarium frame (Fig. 2). If the hanger
doesn't fit, you may need to order separate suction cups (see spare parts list
on back panel to order).
3. Insert the filter cartridge and Bio-Foam
the Bio-Foam is marked "front" and should face the front of the internal filter.)

4. See diagram for positioning and max and min water levels (Fig. 4). To adjust
the height of your filter, simply slide the filter up or down along the hanger
track. If you can't position the filter to your desired water level, you may set
the filter on a sand-free aquarium bottom or you may need to order suction
cups (see spare parts list to order) and set up as shown in Fig. 5.
5. Once the filter and water level is within the recommended parameters,
plug in the filter. Avoid using sand in the aquarium, as this clogs the filter.
