An aquarium air pump pushes air through tubing to air stones, sponge filters or bubblers. The same pumps are also sold for hydroponic buckets and small ponds. The main choices are the number of outlets, the airflow and the wattage.
The six pumps below include four dual-outlet models and two with four outlets. Outlets, airflow and wattage come from each Amazon listing, and several listings give airflow or tank sizes that do not agree with each other, which we point out. We have not used these products ourselves. Noise figures are the makers’ own.
