Anchorstone 12" Sand Airstone

The super porous surface of the Anchorstone Sand Airstone produces a constant bubble flow, which adds much needed oxygen to aquariums for healthy fish.

With its patented anchor feet, the Anchorstone can be securely placed anywhere in the aquarium without the use of suction cups. The Anchorstone is also wider than other air stones, which results in an abundant wall of bubbles. Approximately 12-7/8" x 1-1/8" x 1-3/8" tall.
