Aquarium Air Pumps & Airstones

Air Pumps & Airstones for Fish Tanks

Air pumps and airstones create a steady stream of small bubbles and water circulation within your freshwater and saltwater tanks. These bubbles provide oxygen to your tank if there isn’t enough water movement otherwise. And when they’re used in tandem with an aquarium filter, they can help water move through the filter properly.

Your choice of an air pump depends on the type of aquarium you have, the live plants and fish within your aquarium, and the filtration system you’re using. Common filters include: internal, under gravel, power, canister and wet/dry. And if your tank doesn’t have enough oxygen for your fish, airstones can be used as decorative elements that produce bubbles. The presence of these tiny bubbles also make for an attractive and clear fish-viewing experience.

In addition to the air pumps and airstones themselves, we have a wide variety of aquarium accessories at Petco. Consider an aquarium kit to get you started.
