Usage Tips
Maximize performance and extend the lifespan of your HG138 Air Pump with these best practices:
1. Proper Placement & Installation
- Install Above Water Line: Place the air pump at least 10 inches above the tank if you’re not using a check valve. This prevents water backflow and protects the pump.
- Use Included Check Valves: If installing below water level, connect the included check valves to prevent siphoning and potential water damage.
- Keep Dry & Elevated: Never submerge the pump. Always place it in a dry, well-ventilated location, away from humidity or water splashes.
2. Optimize Airflow for Your Setup
- Adjust Air Volume via the control knob to suit specific needs:
- Gentle bubbles for aquarium fish or corals
- High oxygenation for goldfish or large fish tanks
- Steady aeration for hydroponic systems and deep aquariums (5.9ft or 6.5 ft)
- Distribute evenly using both stainless steel outlets to run multiple air stones, sponge filters, or nano bubblers.
3. Ensure Silent Operation
- Place on Flat Surface: Use the anti-vibration silicone feet and avoid placing it on resonant surfaces like metal or glass shelves.
- Avoid Obstruction: Ensure air tubes are not kinked or pinched to maintain smooth airflow and reduce strain on the motor.
4. Regular Maintenance
- Clean Air Stones Monthly to prevent clogging and loss of pressure.
- Check Tubing & Valves for signs of wear or blockage—replace if airflow weakens.
- Dust the Pump Vents regularly to keep airflow channels clear and prevent overheating.
5. Power & Safety Precautions
- Always connect to UL-certified outlets with a drip loop to protect against electrical hazards.
- Avoid using extension cords and never operate with wet hands.
- Unplug during maintenance or if not in use for extended periods.
