Large, multipurpose aquarium airstones produce loads of decorative and functional air bubbles. Marina Air Stones create a dazzling underwater scene thanks to their large size that supplies your aquarium with plenty of bubbles for improved aeration and water circulation. Diffused air increases surface agitation to promote proper gas exchange that accelerates oxygen replenishment while reducing carbon dioxide buildup. Marina Air Stones are available in 4", 6", and 12" lengths. Fits standard airline tubing.
Airstones require an air pump and airline tubing for use (sold separately).
