Air Stone Cylinder 3 cm ZOLUX - aquarium aeration accessory

ZOLUX Air Stone Cylinder 3 cm is an aquarium aeration accessory designed to diffuse air into water and produce a steady flow of fine bubbles. The compact cylindrical shape fits small tanks, ornaments, and filtration outlet tubes. When connected to an air pump and tubing, this air stone helps increase dissolved oxygen levels and improves circulation in confined aquarium spaces, supporting fish respiration and overall water movement.

Advantages

The air stone generates uniform microbubbles that enhance gas exchange without creating strong currents that could stress small or delicate species. Its small size makes it easy to place discretely inside decorations or near substrate, while the cylindrical form ensures an even distribution of bubbles along its length. The device is compatible with standard aquarium tubing and common air pump setups, offering a simple, low-maintenance way to improve oxygenation.

Suitable for

• Small and nano aquariums requiring gentle aeration
• Planted tanks where minimal water disturbance is preferred
• Ornamental setups where the air stone can be hidden inside decorations
• Assisting filtration outlets to diffuse air and improve circulation

Key specifications

• Form factor: cylindrical aeration stone
• Length: 3 cm
• Material: porous aeration stone (fine-pored)
• Connection: compatible with standard aquarium air tubing
• Function: produces fine bubbles to increase oxygenation and water circulation

How to use

Attach one end of standard aquarium air tubing to an appropriate air pump and the other end to the air stone. Submerge the air stone fully in the aquarium, positioning it where gentle circulation is desired—near the substrate, behind decorations, or close to filter outlets. Turn on the air pump and check bubble production; adjust the pump’s flow or add an inline valve if bubble size or intensity requires tuning. Periodically inspect the air stone for clogging and replace it if bubble output declines significantly.

Usage recommendations

For best performance, use with an air pump sized appropriately for the aquarium volume and include an in-line check valve to prevent backflow. Clean or replace the air stone every few months depending on water conditions and biofilm accumulation. Avoid strong currents for planted tanks and delicate species by reducing pump output or moving the air stone to a less exposed location.
