The Marina Air Stone diffuses water in every direction, creating a dazzling underwater display. The constant stream of bubbles increases surface agitation, adds oxygen to the aquatic environment and helps release carbon dioxide build-up for safe aquarium water and healthy fish.

• Oxygenates water for a healthy aquatic environment
• Improves circulation and releases carbon dioxide buildup
• Decorative deep blue color matches almost any aquarium

Marina Air Stones fit standard (3/16") airline tubing. Safe for fresh or saltwater aquariums.

Note: Requires air pump (not included).
