Setup and Installation
Follow these simple steps to set up your hygger Mini Air Pump:
- Connect Air Tubing to Pump: Firmly attach one end of the flexible air tubing to the air outlet nozzle on the hygger Mini Air Pump.
- Connect Air Tubing to Air Stone: Attach the other end of the air tubing to the inlet of the mini air stone bubbler. Ensure a snug fit.
- Attach Suction Cup: Secure the double-sided suction cup to the back of the air pump. This allows you to mount the pump securely to the outside glass of your aquarium or fish bowl.
- Position Air Pump: Install the air pump higher than the water level of your aquarium to prevent water backflow. Use the suction cup to fix it to the outside of the tank.
- Place Air Stone: Carefully lower the air stone into your aquarium. For best results, the air stone should be soaked in water for 1-2 hours before first use to ensure even bubble distribution.
- Power On: Plug the power adapter into a standard AC 110V/60Hz electrical outlet. The pump will immediately begin to produce bubbles.

Operating Instructions
Once installed, the hygger Mini Air Pump operates continuously to provide aeration. No further adjustments are typically needed for basic operation. Ensure the air stone is fully submerged and free from obstructions to allow for optimal bubble production.
- Verify that the air pump is securely mounted above the water level.
- Confirm that the air tubing is not kinked or blocked, which could restrict airflow.
- Observe the air stone to ensure a steady stream of fine bubbles is being produced.
Maintenance
Regular maintenance will help prolong the life and efficiency of your air pump:
- Air Stone Cleaning: Over time, air stones can become clogged with algae or mineral deposits, reducing bubble output. Periodically remove the air stone and clean it by gently scrubbing with a soft brush under running water. If severely clogged, consider replacing it.
- Tubing Inspection: Check the air tubing regularly for any kinks, cracks, or blockages. Replace if necessary to ensure uninterrupted airflow.
- Pump Exterior: Wipe the exterior of the air pump with a dry cloth to keep it clean. Do not submerge the pump in water.
