These Japanese Ceramic Air Stones, which whilst being much more expensive to buy do offer a much finer and intense air diffusion and do last much longer and therefore do not need replacing quite so often.
These high quality long life air stones are made from a refined ceramic compound. They produce 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 from any surrounding surfaces.
