Safety Information
- Always disconnect the power supply before performing any maintenance, installation, or cleaning.
- Ensure the filter is fully submerged in water during operation. Running dry can damage the motor.
- Do not operate if the power cord or plug is damaged.
- This appliance is for indoor use only and intended for aquariums.
- Keep out of reach of children.
- Ensure a drip loop is formed with the power cord to prevent water from traveling along the cord and reaching the electrical outlet.
Package Contents
The Vehipa GL-1603F Aquarium Filter package includes:
- Aquarium filter unit
- Bio sponge filter media
- Duckbill mouth (output nozzle)
- Oxygen tube
Setup Instructions
- Unpack Components: Carefully remove all parts from the packaging and inspect for any damage.
- Assemble Filter Media: Insert the bio sponge filter media into the designated compartments within the transparent filter body. You may customize with additional media like ceramic bio-rings or activated carbon (not included) if desired.
- Attach Output Nozzle: Connect the duckbill mouth (output nozzle) to the filter head. This nozzle can be adjusted 180 degrees to direct water flow.
- Connect Oxygen Tube: If using the oxygenation feature, attach the oxygen tube to the air intake port on the filter head. Ensure the other end of the tube is above the water surface.
- Position Filter: Submerge the filter completely in your aquarium. Use the three powerful suction cups on the back of the filter head to securely fasten it to the glass surface of the aquarium. Ensure the filter is placed vertically.
- Check Water Level: Verify that the water level in your aquarium is above the minimum water line indicated on the filter. The filter must be fully submerged to operate correctly.
- Connect Power: Once the filter is securely installed and fully submerged, connect the power cord to a suitable electrical outlet. Ensure a drip loop is in place.

Operating Instructions
- Power On: Once plugged in, the filter will begin operating.
- Adjust Water Flow Direction: The duckbill output nozzle can be rotated 180 degrees to direct the water flow as needed for optimal circulation or wave-making.
- Adjust Oxygenation: If the oxygen tube is connected, you can adjust the air flow using the adjustable oxygen valve to control the amount of bubbles generated.
- Monitor Operation: Observe the filter to ensure proper water circulation and oxygenation. The transparent body allows for visual inspection of filter media and debris collection.
Maintenance
Regular maintenance is crucial for the longevity and efficiency of your aquarium filter.
- Disconnect Power: Always unplug the filter from the power outlet before any cleaning or maintenance.
- Remove Filter from Aquarium: Carefully detach the filter from the aquarium glass.
- Disassemble Filter: Gently separate the filter components, including the filter head, transparent body, and debris collection chamber.
- Clean Filter Sponges: Remove the bio sponge filter media. Rinse them thoroughly in old aquarium water (from a water change) to preserve beneficial bacteria. Avoid using tap water directly, as chlorine can kill these bacteria. Replace sponges if they are heavily degraded.
- Clean Debris Collection Chamber: Empty and rinse the debris collection chamber to remove accumulated waste. The transparent design makes it easy to see when this needs cleaning.
- Clean Impeller: Periodically, remove the impeller from the filter head and clean it and its housing to ensure smooth operation and prevent blockages.
- Reassemble and Reinstall: Once all components are clean, reassemble the filter and reinstall it in the aquarium following the setup instructions.
- Power On: Plug the filter back into the power outlet.
