The AQUATOP Aquarium Air Pump delivers a powerful punch with low energy consumption and super quiet operation. Aquarium air pumps allow your aquatic creatures to acquire the oxygen they need in order to thrive. An air pump system adds air bubbles, creates current and agitates the water to help in filtration. This is where the quiet hum noise of most aquariums comes from. An air pump also aids in maintaining stable and healthy pH levels inside the aquarium.
