Aqua One Airstone 3/4 Inches 3pk

Airstones play a valuable role in aquariums by replacing oxygen in the water. By breaking the surface tension of the water, oxygen may be absorbed into the water to replenish the supply used by your fish and the filtration process. Well oxygenated water is one of the keys to a health aquarium, and this 3 pack of 3/4in cylinder style airstone will create an attractive and efficient bubble flow in your tank.
