## Summary description

Hagen air stone sphere 3 cm designed for aquarium aeration. This ceramic or porous aerator produces fine bubbles to improve oxygenation and water circulation in freshwater and marine tanks. Suitable for use with air pumps and tubing, ideal for increasing dissolved oxygen, reducing dead zones, and supporting fish and plant health in home aquariums.

## Long description

Hagen Air Stone Sphere 3 cm is a compact aquarium aeration accessory designed to produce a steady stream of fine bubbles for improved oxygenation and water movement. The spherical aerator is made from a porous ceramic material that diffuses air into many small bubbles, supporting gas exchange and reducing stagnant zones in both freshwater and marine tanks. It connects to standard airline tubing and air pumps to enhance dissolved oxygen levels and promote a healthier environment for fish and aquatic plants.
Advantages
The round ceramic design creates uniform, fine bubbles that increase the surface area for gas exchange and improve oxygen distribution within the tank. Its small 3 cm size fits easily into planted aquariums and decorative layouts without occupying much space. The durable porous material resists clogging under normal conditions and provides consistent performance with compatible air pumps and tubing.
Suitable for
Small freshwater aquariums where gentle aeration is required
Marine tanks needing supplemental gas exchange and circulation
Planted aquariums to prevent dead zones and support root and leaf respiration
Quarantine or hospital tanks to maintain higher dissolved oxygen levels
Key specifications
Shape: spherical aeration stone
Approximate diameter: 3 cm
Material: porous ceramic aerator
Output: produces fine bubbles for improved oxygenation and micro-circulation
Compatibility: designed for use with standard aquarium airline tubing and air pumps
How to use
Attach one end of appropriate airline tubing to the outlet of a compatible air pump and the other end to the aerator. Position the air stone on the aquarium floor or among decorations, ensuring it rests stably and is fully submerged. Adjust the air pump flow rate to produce a steady stream of fine bubbles; reduce flow if bubbles are too large or disruptive to tank inhabitants. Periodically inspect the aerator and tubing for blockages or wear and clean or replace components as needed.
Usage recommendations
For best results, place the sphere where circulation is beneficial but not directly under delicate plants or corals that may be disturbed by constant bubbling. Clean the aerator gently by soaking in clean water and using soft brushing if mineral deposits build up; avoid harsh chemicals. Match pump output to the aerator size to maintain efficient, quiet operation and stable oxygen levels.
