Airstone 4″ ( 10cm )

Air stones are a great way to aerate your aquarium. By breaking the surface tension of the water, oxygen may be absorbed into the water. Filtration system performance and overall water quality will be greatly improved with a greater oxygen content in the water. Description

• Increases water circulation
• Bubbles make a great feature in any aquarium

To achieve a healthy amount of bubbles you may desire from your airstone, please remember that the longer the airstone, the bigger/stronger the air pump needs to be to make it work effectively.
