An airstone, also called an aquarium bubbler, is a piece of aquarium furniture, traditionally a piece of limewood or porous stone, whose purpose is to gradually diffuse air into the tank, eliminating the noise and large bubbles of conventional air filtration systems, and providing other benefits to the health of the fish. "Airstone" is also a brand name stone or brick veneer used by homebuilders. Airstones are sold in a very wide variety of shapes, sizes, and levels of coarseness – from extremely rough, producing larger bubbles and letting in more oxygen – to very fine, producing minuscule bubbles. Airstones are increasingly being made from bonded glass beads and synthetic products like fiberglass.
