## Summary description

ZOLUX air stone, 13 cm length, designed for aquarium aeration and improved water circulation. This air diffuser produces fine bubbles when connected to an external air pump or compressor, increasing oxygenation and supporting filtration efficiency. Suitable for freshwater and saltwater tanks, it helps maintain healthy conditions for fish, shrimp and plants.

## Long description

ZOLUX 13 cm Air Stone is a ceramic air diffuser designed to improve aeration and water circulation in freshwater and marine aquariums. When connected to an external air pump or compressor, the diffuser releases a steady flow of fine bubbles that enhance oxygen exchange at the water surface and support mechanical and biological filtration by keeping particles in suspension. The 13 cm length provides an extended area of bubble output for more even dispersion across small to medium tanks.
Advantages
The ceramic construction ensures consistent bubble size and long-term durability while resisting clogging under normal aquarium conditions. Its elongated shape offers broader coverage than small round stones, promoting improved water movement and oxygen distribution. Compatible with standard airline tubing, the air stone is easy to integrate with existing aeration systems and requires minimal maintenance.
Suitable for
Freshwater aquariums with fish, shrimp and live plants
Saltwater aquariums where gentle aeration is needed
Improving oxygenation in tanks with high bioload or limited surface agitation
Supporting filtration systems by preventing detritus settling
Key specifications
Material: ceramic air-diffusing medium
Length: 13 cm
Shape: elongated cylindrical diffuser
Connection: compatible with standard airline tubing
Bubble output: fine bubble dispersion for efficient oxygen transfer
How to use
Connect the air stone to an appropriate external air pump or compressor using standard airline tubing, ensuring an airtight fit. Place the diffuser horizontally or vertically near the tank bottom or at a location that promotes desired circulation patterns; avoid placing it directly against substrate that could block the pores. Start with moderate air flow and adjust the pump output to achieve a steady stream of fine bubbles without excessive turbulence.
Usage recommendations
Rinse the air stone under clean water before first use to remove any dust. Periodically inspect the diffuser; if bubble output diminishes, gently clean by soaking in a solution of water and mild vinegar to dissolve mineral deposits, then rinse thoroughly. Replace the diffuser if clogging cannot be cleared or if ceramic shows damage. Use with appropriate pump size for tank volume to avoid over-aeration.
