These high quality long life air stones are made from a refined ceramic compound. They produce a very fine aeration and can be used in conjunction with any good air pump. All of the ceramic air products listed have plastic end housings which protect the air stone against abrasive contact with surrounding surfaces (except the 50mm ball type).
