FZONE Aquarium Air Pump, Ultra Quiet Aerator Pump for Freshwater and Saltwater Aquariums

Why Do Aquariums Need an Air Pump? An air pump plays a vital role in an aquarium by increasing oxygen levels and promoting water circulation. It pushes air through tubing into air stones or filters, creating bubbles that enhance gas exchange (oxygen in, carbon dioxide out). This helps fish breathe better, beneficial bacteria thrive, and prevents stagnant areas in the tank. It’s also commonly used to power sponge filters, air-driven decorations, and protein skimmers, keeping the aquarium healthy and lively. Warm Tips: The pump is NOT SUBMERSIBLE, please do not put it into the aquarium. Keep it dry. Clean air tubes and stones regularly for best airflow and longer lifespan. Connect up to 4 devices max; water depth ≤ 5 ft. Without a check valve, the air pump should be placed above the water level. When a check valve is installed (ensure correct direction), the pump can be positioned below the water surface or on a tabletop to prevent backflow. Where Should Aqaurium Air Pump Be Placed?
