This small almost silent air pump is great for nano tanks. It also is a decent choice for adding an air stone to an existing larger tank. Our air pump runs off USB power, which means it's great in a power outage situation with a battery pack, the pump also is very low voltage compared to other air pumps. It is very helpful if you get new fish and have a long trip in your car.
The amount of air that the pump produces is lower than most air pumps which help it be more quiet and use less power. Great for smaller sponge filters or our air stones.
It comes with an airstone and airline hose.
