The Ceramic 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 stones have plastic 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.
The Budget airstones are perfect for hobbyists and pond owners. Though they will need to be replaced more often than ceramic airstones, they do offer a good solution to providng your pond with much-needed air.
This Long life flat aeration disc is ideal for use with large ponds and large air pumps.
The 200mm and 132mm Diameter air discs with a large surface area will be ideal for delivering high amounts of oxygen into a pond or quarantine tank, also for agitating Kaldnes (K1) as well.
