## Summary description

ZOLUX air-stone cylinder 4 cm is an aquarium aeration accessory designed to produce fine bubbles and improve water oxygenation. The compact cylindrical diffuser connects to standard airline tubing to distribute air from pumps or compressors, enhancing circulation and supporting fish and plant health. Suitable for freshwater and marine tanks where gentle aeration and surface agitation are needed.

## Long description

ZOLUX air-stone cylinder 4 cm is a compact ceramic bubbling diffuser designed to improve oxygenation and circulation in aquariums. The cylindrical shape produces fine, consistent bubbles that increase gas exchange at the water surface and promote gentle water movement. It connects to standard airline tubing and is compatible with most aquarium pumps and compressors, providing a simple way to support fish and plant health in both freshwater and marine tanks.
Advantages
The ceramic construction delivers long-lasting, uniform diffusion and resists clogging when maintained correctly. Its small 4 cm size makes it suitable for tanks where space is limited or where subtle aeration is desired. The diffuser’s even bubble output supports stable oxygen levels and reduces dead zones by gently circulating water without creating strong currents that can stress sensitive species.
Suitable for
 Freshwater aquariums requiring gentle aeration
 Marine tanks where subtle surface agitation is needed
 Planted tanks that benefit from improved CO2 exchange and circulation
 Small to medium tanks where compact accessories are preferred
Key specifications
 Material: ceramic diffuser body
 Shape and size: cylindrical, 4 cm length
 Connection: fits standard airline tubing
 Bubble type: fine, consistent microbubbles
 Intended use: aquarium aeration and water circulation
How to use
Attach the ZOLUX air-stone cylinder to standard airline tubing and connect the tubing to an appropriate air pump or compressor. Position the diffuser near the aquarium bottom or where gentle upwelling is desired; the rising fine bubbles will promote surface agitation and improve oxygen transfer. For best results, ensure the air pump provides steady, adjustable flow compatible with the small-diameter diffuser to avoid oversized bubbles or uneven output.
Usage recommendations
Rinse the ceramic diffuser in aquarium water before first use to remove any residual dust. Periodically inspect and, if necessary, clean the diffuser by soaking it briefly in dechlorinated water and gently brushing the surface with a soft brush; avoid harsh chemicals. Replace the diffuser if pores become irreversibly clogged or if bubble output declines significantly. Use with appropriately sized pumps to maintain fine bubble production and prevent excessive flow through the ceramic element.
