Biorb Airstone x 1

Description

Suitable for all biOrb aquariums, the biOrb Air Stone is designed to fit perfectly in the base of the biOrb, underneath the filter cartridge. It breaks up the flow of air into the aquarium, splitting it into a mass of fine bubbles. 

Air stones work to circulate the air around your fish tank by producing tiny bubbles filled with oxygen. These bubbles not only work to fill your fish tank with oxygen but they also work to circulate the fish tank water by lifting the different layers within the tank to the top of the aquarium.
