## Summary description

HAPPET aeration stone in a 5 cm spherical form designed for aquarium and pond oxygenation. The porous stone produces fine bubbles when connected to an air pump, supporting water circulation and gas exchange. Suitable for improving oxygen levels, reducing stratification, and creating gentle water movement in small to medium aquatic setups.

## Long description

HAPPET aeration stone sphere 5 cm is a porous, spherical air diffuser designed for aquarium and pond oxygenation. When connected to an external air pump, the 5 cm stone generates a steady flow of fine bubbles that improve gas exchange and support gentle water circulation. The compact spherical shape fits small and medium aquatic setups and helps reduce water stratification while enhancing oxygen distribution across the water column.
Advantages
The porous ceramic structure produces uniform, fine bubbles that increase dissolved oxygen efficiently without strong currents. Its compact 5 cm diameter sphere is easy to position and conceals well among decorations or substrate. Durable, inert material resists water degradation and does not alter water chemistry. The diffuser is compatible with standard low-pressure air pumps and tubing used in home aquariums and ornamental ponds.
Suitable for
Freshwater aquariums up to small/medium volume
Outdoor decorative ponds and water features
Breeding tanks and fry rearing where gentle aeration is needed
Hydroponic or biological filter systems requiring increased oxygenation
Key specifications
Shape: sphere
Diameter: 5 cm
Material: porous ceramic (inert, non-reactive)
Output: produces fine bubbles suitable for low-pressure air pumps
Installation: requires external air pump and silicone tubing
How to use
Connect the aeration stone to an appropriately sized air pump using flexible silicone tubing. Place the stone on the tank or pond bottom or bury partially in the substrate for a concealed installation. Start the pump and adjust airflow at the pump or with an inline valve to achieve the desired bubble size and circulation strength. Periodically inspect the stone for clogging and clean gently if bubble output decreases.
Usage recommendations
For best performance, use an air pump with suitable output for the aquarium volume and maintain regular cleaning to prevent blockage. Avoid aggressive scrubbing that could damage the porous surface; soak in dechlorinated water and rinse gently. Positioning the stone near filtration outflow can enhance circulation while preventing stagnant zones.
