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 cylinder ceramic air stones have rubber end housings which protect the air stone against abrasive contact from any surrounding surfaces.

This added protection provides long life and trouble free operation of the units.

Ceramic stones can be cleaned every 6 months in 100% Muriatic Acid to clean calcium and organic buildup and return to like-new performance.
