• Filter Cover: Protects internal components.
• Adjustable Flow Knob: Controls water flow rate.
• Intake Tube: Draws water from the aquarium.
• Surface Skimmer: Removes oil film and debris from the water surface.
• Surface Skimmer Seat: Connects the skimmer to the intake tube.
• Extension Tube (x2): Extends the intake tube for deeper tanks.
• Strainer: Prevents large debris and fish from entering the intake.
• Filter Cartridge (x2): Contains multi-layer filtration media.
• Porous Bio-Sponge: Provides biological filtration.
• Filter Box: Houses the filter media.
• Alignment Wheel: Secures the filter to the tank glass.
• Filter Foam (x2): Additional mechanical filtration.

Setup

1. Assemble the Intake System: Attach the strainer to the bottom extension tube, then connect the extension tubes together if needed, and finally attach the assembly to the main intake tube. Secure the surface skimmer to its seat on the intake tube.
2. Install Filter Media: Ensure the filter cotton is installed correctly within the filter cartridges. The activated carbon cotton should face the fish tank, while the foam cotton should face outward.
3. Prepare Filter Cartridges: Before initial use, fully soak the filter elements in aquarium water to ensure effective filtration and prevent air pockets.
4. Mount the Filter: Hang the assembled filter on the side of your aquarium. Adjust the alignment wheel to ensure there is no gap between the filter and the fish tank glass. This helps reduce noise and vibration.
5. Fill with Water: Pour water into the filter box until the water level exceeds the indicated label position. This primes the pump and prevents dry operation.
6. Power On: Plug the filter into a power outlet. Ensure the plug is inserted tightly. The pump should start working. If it does not work after 1 minute, add more water to the filter box.
7. Adjust Flow: Close the filter cover and adjust the water flow using the adjustable flow knob on top of the filter.

Operating Instructions

Water Flow and Oxygenation

The filter provides a high flow rate of 172 GPH (gallons per hour) and features dual waterfalls. These waterfalls increase water circulation and oxygen content in your aquarium, which is beneficial for fish health.

Adjusting Water Flow

Use the adjustable flow knob located on the top of the filter to increase or decrease the water flow. This is particularly helpful when feeding your fish, allowing you to temporarily reduce the current.

Surface Skimmer Function

The efficient surface skimmer automatically floats with the water level, effectively removing oil film and floating debris from the water surface. This helps maintain clear water and prevents impurities from accumulating.

Quiet Operation

The filter is designed for quiet operation, typically below 36 dB, thanks to its durable ABS material and high-quality water pump rotor. For optimal quietness, ensure the water level in the aquarium is close to the filter's outlet.

Maintenance

Regular maintenance is crucial for the optimal performance and longevity of your filter.

• Filter Cleaning: It is recommended to clean the filter every 15 days. Unplug the filter, remove the filter cartridges, and rinse them thoroughly with old aquarium water (not tap water, to preserve beneficial bacteria).
• Filter Media Replacement: Replace the filter box/cartridges every 60 days, or sooner if they appear heavily clogged or dirty.
• Rotor Cleaning: If you notice abnormal noise or reduced flow, inspect and clean the rotor. Turn off and unplug the product. Carefully open the relevant parts to access the rotor. Use a soft-bristle brush or compressed air to gently remove any impurities.
• Intake Tube Cleaning: The intake tube, especially near the strainer, can accumulate biofilm. Periodically remove the intake guard and dislodge any clogs with your finger, then clean the guard.

Troubleshooting

This section addresses common issues you might encounter with your lychee External Hang-On Aquarium Filter QF-09.

Malfunction: Not Working

• Check the Plug: Ensure the power plug is inserted tightly into the outlet. A loose connection can prevent power supply. Unplug and firmly re-insert.
• Check the Water Level: Verify that the water level in the aquarium is above the minimum inlet mark and that the filter basket water level is above 50%. If the water level is too low, the product may not function properly. Add water to the recommended mark.
• Check the Water Supply Pipe: If you hear the motor running but no water is being drawn, check the water supply pipe for loose connections or blockages. Gently twist and fasten pipe connections to ensure they are tight.
• Motor Failure: If the product still shows no response after checking the above, it might be due to a motor failure. Do not attempt to repair the motor yourself. Contact customer support for replacement.

Malfunction: Abnormal Noise

• Normal Operating Sound: The filter will produce a certain sound during operation due to internal components like motors and impellers. Familiarize yourself with this normal sound to distinguish it from abnormal noises.
• Check and Clean the Rotor: Impurities lodged inside the rotor can cause imbalance and abnormal noise. Turn off and unplug the filter, then carefully access and clean the rotor with a soft brush or compressed air.
• Check the Fixed Knob: Ensure there is no gap between the filter's fixed knob and the fish tank glass. A gap can cause vibration and noise. Tighten the fixed knob to secure the product and reduce vibration.

Malfunction: Water Leakage and Weak Water Flow

• Check the Rubber Stopper: Use a tool to pry open the base and check the rubber stopper. A damaged or misaligned rubber stopper can lead to water leakage. Inspect for wear, cracks, or displacement. Replace if damaged.
• Check the Water Level: A low water level can cause weak water flow. Ensure the water level is sufficient to ensure normal flow performance.
• Adjust the Water Volume Knob: Turn the water volume knob to the maximum position. Sometimes, the water flow rate may be set too low.
• Check and Replace the Filter Element: A clogged filter element can restrict water flow. Remove the filter element and visually inspect it. If it appears dirty or blocked, replace it with a new one to restore normal water flow.
