4. Setup Instructions

Prepare the Filter Media: Rinse the biochemical sponge and ceramic balls thoroughly with aquarium water or dechlorinated tap water before placing them into the filter compartments. This removes any manufacturing dust.
Assemble the Filter: Ensure all filter media are correctly seated within the filter body. Attach the dual water outlet nozzles to the top of the filter unit.
Mounting: Attach the suction cups to the filter body. Submerge the filter completely in your aquarium. Press the suction cups firmly against the inner glass wall of the aquarium to secure the filter in place. Ensure the filter is positioned vertically and is fully underwater.
Water Level: The water level in the aquarium must always be above the minimum water line indicated on the filter, ensuring the motor is fully submerged.
Optional Water Pipe Connection: If using the filter for water pumping (e.g., for water changes), connect a user-prepared water pipe to the designated outlet.

Diagram showing the filter being used as a pump to remove water from the aquarium into a bucket — Figure 4.2: The filter can also function as a water pump. A user-supplied water pipe is required for this application, directing water out of the aquarium.

5. Operation

Power On: Once the filter is securely mounted and fully submerged, plug the power cord into a suitable electrical outlet. The filter will begin operating immediately.
Adjusting Water Flow: The filter features an adjustable flow rate. Locate the flow adjustment lever (if present) and slide it to increase or decrease the water output. The maximum flow rate is 900L/H.
Dual Water Outlet: The dual water outlets provide versatile water circulation. You can adjust their direction to create desired water movement and aeration within the aquarium.
Aeration: If an air tube is connected, adjust the air intake to control the amount of air bubbles for oxygenation. Note that excessive aeration can sometimes increase operational noise.

6. Maintenance

Regular maintenance is crucial for the longevity and efficiency of your filter and the health of your aquarium. Perform maintenance at least once every 2-4 weeks, or more frequently if water clarity decreases.

Disconnect Power: Always unplug the filter from the power outlet before beginning any maintenance.
Remove from Aquarium: Carefully detach the filter from the aquarium wall and remove it from the water.
Disassemble: Gently separate the filter housing components to access the filter media and impeller chamber.
Clean Filter Media: Rinse the biochemical sponge and ceramic balls with old aquarium water (from a water change) to preserve beneficial bacteria. Do not use tap water directly, as chlorine can kill these bacteria. Replace filter media as needed (typically every 3-6 months for sponges, ceramic balls last longer).
Clean Impeller: Remove the impeller cover and carefully extract the impeller. Clean the impeller and its chamber with a small brush to remove any debris or algae buildup. Ensure the impeller spins freely.
Clean Housing: Rinse the filter housing and outlet nozzles with aquarium water.
Reassemble and Reinstall: Reassemble all components in reverse order. Ensure all parts are securely fitted. Reinstall the filter in the aquarium, ensuring it is fully submerged before plugging it back in.
