4. Assembly and Setup
4.1 Filter Pump Assembly
The 3-in-1 filter pump is crucial for water circulation, oxygenation, and filtration. Follow these steps for assembly:
- Attach the water intake with foam to the bottom of the water pump.
- Connect the Ranin Pipe (water outlet pipe) to the pump's outlet.
- Attach the air tube to the T-connector, then connect the T-connector to the pump's air intake. Ensure the oxygen pipe is positioned above the water level for aeration.
- Secure the assembled pump unit inside the aquarium using the fixing buckle or suction cups provided.

4.2 Aquarium Placement and Filling
- Choose a location away from direct sunlight, heat sources, and drafts.
- Rinse the tank and any decorations thoroughly with clean water (do not use soap or detergents).
- Add substrate (gravel or sand) if desired, then place decorations.
- Carefully fill the tank with dechlorinated water, leaving a small gap from the top rim.
- Place the lid securely on the aquarium.
5. Operation
5.1 Filter System
Once the tank is filled and the pump is assembled, plug in the pump. The 120 GPH pump will begin circulating water, providing filtration and aeration. The filter sponge helps remove debris and odors, while beneficial bacteria colonize to maintain water quality.

6. Maintenance
6.1 Routine Cleaning
- Glass Cleaning: Use an aquarium-safe cleaner or magnetic algae scraper to clean the interior glass surfaces as needed.
- Water Changes: Perform regular partial water changes (e.g., 25% weekly) to maintain water quality. Always use dechlorinated water.
- Substrate Cleaning: Use an aquarium gravel vacuum during water changes to remove debris from the substrate.
6.2 Filter Cartridge Replacement
The filter cartridge should be replaced regularly (typically every 2-4 weeks, depending on bioload) to ensure effective filtration. Replacement cartridges can be found by searching for B094R5CV51.
- Unplug the filter pump.
- Carefully remove the old filter cartridge from the filter housing.
- Insert a new filter cartridge into the housing.
- Reconnect the filter pump to power.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Filter pump not working | Power outage, clogged impeller, pump failure | Check power connection. Unplug, clean impeller and housing, then re-plug. If still not working, pump may need replacement. |
| Water flow from filter is too strong | High pump output for small fish | Some users report strong flow for Betta fish. Consider adding a flow diffuser or adjusting the oxygen pipe to reduce direct current. |
| Aquarium is leaking | Seal failure, crack in glass | Immediately drain water to prevent damage. Inspect for cracks. For minor seal issues, aquarium-safe silicone sealant may be applied after thorough drying. If a crack is present, the tank should be replaced. |
| LED light not working | Power issue, light unit malfunction | Ensure the power cord is securely plugged in. Press and hold the control knob to turn the light on/off. If still unresponsive, contact customer support. |
| Temperature display inaccurate or blank | Sensor issue, display malfunction | Verify the temperature probe is fully submerged. If the issue persists, contact customer support. |
