## Summary description

Hagen KAMIEŃ NAPOWIETRZAJĄCY is a small cube-shaped aeration stone (2.5 x 2.5 cm) designed for aquarium use. It produces fine bubbles when connected to an air pump, improving oxygenation and water circulation. Suitable for small tanks, decoration zones, and biological filtration setups where gentle aeration and even bubble distribution are needed.

## Long description

Hagen aeration stone cube 2.5 x 2.5 cm for aquariums — KAMIEŃ NAPOWIETRZAJĄCY 008914 is a compact, cube-shaped porous air stone designed to generate a steady flow of fine bubbles in planted and ornamental aquariums. Connecting to a standard aquarium air pump via flexible tubing, the 2.5 x 2.5 cm cube improves oxygen transfer at the water surface and enhances gentle circulation without creating strong currents. Its small size makes it suitable for confined spaces, decorative arrangements and biological filtration setups that require even aeration distribution.
Advantages
The aeration stone produces fine, consistent bubbles that promote efficient oxygenation and better gas exchange in the aquarium water. Its cube form and compact dimensions allow discreet placement behind decor or inside filter chambers while maintaining stable performance. Made from porous material, the stone resists rapid clogging under normal aquarium conditions and provides uniform bubble output, which supports aerobic bacteria in biological filters and helps reduce stagnant zones.
Suitable for
 Small and nano aquariums requiring gentle aeration
 Planted tanks where minimal water disturbance is desired
 Decoration areas where an unobtrusive bubble effect is needed
 Biological filter chambers or media beds that benefit from constant oxygen supply
Key specifications
 Shape: cube
 Dimensions: 2.5 x 2.5 cm
 Material: porous aeration stone material suitable for aquarium use
 Output: produces fine bubbles for gentle oxygenation and circulation
 Compatibility: connects to standard aquarium air pumps via tubing
How to use
Connect the aeration stone to an aquarium air pump using suitable flexible tubing and place the stone in the desired location inside the aquarium or filter chamber. Positioning the cube on the substrate, behind decor or inside a filter compartment will determine bubble pattern and water movement. Use an adjustable air pump or an inline valve to control bubble intensity and oxygenation level appropriate for tank inhabitants.
Usage recommendations
Rinse the aeration stone in clean water before first use to remove loose particles. Periodically inspect and, if necessary, clean the stone by soaking it briefly in a diluted vinegar solution or by gently brushing under running water to remove deposits; avoid harsh chemicals. Match air pump output to the cube size to prevent over-aeration in very small tanks.
