## Summary description

## Long description

Hagen KAMIEŃ NAPOWIETRZAJĄCY KULA 2 cm is a 2 cm spherical aeration stone intended for aquarium oxygenation. Made for connection to standard airline tubing and compatible with most air pumps, the aeration stone generates a steady stream of fine bubbles that enhance gas exchange and water circulation in freshwater and marine tanks. Its compact spherical shape makes it suitable for small aquaria, breeding setups and localized aeration near filters or biological media.
Advantages
The aeration stone produces consistent fine bubbles that increase dissolved oxygen and support aerobic biological filtration. Its small 2 cm diameter sphere provides localized diffusion while occupying minimal space within the tank. The inert material resists breakdown in both fresh and saltwater environments and is simple to install and reposition as needed.
Suitable for
Small aquariums and nano tanks
Breeding and fry rearing setups
Enhancing water circulation near filters or sponge media
Supplemental oxygenation in planted or lightly filtered systems
Key specifications
Shape: spherical aeration stone
Diameter: approximately 2 cm
Material: inert porous stone suitable for aquarium use
Connection: compatible with standard airline tubing
Application: suitable for freshwater and marine aquaria
How to use
Attach a piece of airline tubing between the air pump outlet and the aeration stone. Submerge the stone in the desired location within the aquarium and secure the tubing to prevent movement; the stone can be placed near the substrate, close to filtration media, or where additional circulation is required. Adjust the air pump flow to obtain the preferred bubble size and coverage; ensure the pump is appropriate for the tank volume to avoid excessive turbulence in small setups.
Usage recommendations
Periodically inspect the aeration stone for clogging and clean it by soaking in aquarium water and gently brushing or using a weak acid rinse according to manufacturer guidance to restore bubble diffusion. Monitor water quality and oxygen levels after installation to confirm adequate aeration for your specific stock and setup.
