## Summary description

ZOLUX 5 cm air stone for aquarium aeration. Designed to diffuse air from external pumps or airline tubing into fine bubbles to improve water oxygenation and circulation. Compact 5 cm size fits standard tubing connections and is suitable for small tanks, desktop aquariums, and localized aeration near filters or decorations.

## Long description

The ZOLUX 5 cm air stone is a compact aquarium aeration accessory designed to diffuse air from external pumps or airline tubing into fine bubbles that improve water oxygenation and circulation. Its 5 cm length and standard connection diameter make it compatible with common airline tubing and small external pumps. The stone's size and bubble output are intended for small tanks, desktop aquaria, and targeted aeration near filters, plants, or decorative elements.
Advantages
The air stone produces a steady stream of fine bubbles that increase gas exchange at the water surface and promote more uniform circulation without strong currents. Its compact form factor allows discreet placement in limited spaces and provides localized aeration where plants and fish need it most. Constructed from a porous material formulated for consistent diffusion, the stone is simple to install and replace as part of routine aquarium maintenance.
Suitable for
Small freshwater and saltwater aquaria
Desktop and nano tanks requiring localized aeration
Supplemental aeration near filters, heaters, or planted zones
Air pump systems and airline tubing setups
Key specifications
Length: 5 cm
Material: porous diffusion stone (non-reactive to aquarium water)
Connection: fits standard airline tubing
Bubble type: fine bubble diffusion for increased surface agitation
Intended use: indoor aquarium aeration and circulation enhancement
How to use
Connect the ZOLUX 5 cm air stone to an appropriate air pump using standard airline tubing, ensuring a secure fit to prevent air leaks. Position the stone at the desired location in the aquarium—on the substrate, behind decorations, or near a filter outflow—to achieve the required bubble coverage. Adjust pump flow or install a control valve if necessary to regulate bubble size and intensity. Periodically inspect the stone for clogging from debris or biofilm and replace it when bubble production becomes uneven or diminished.
Usage recommendations
For best results, pair the air stone with an air pump sized for the aquarium volume and consider using a check valve to prevent backflow. Clean or replace the stone during routine maintenance; soaking in clean water and gentle brushing can extend service life but avoid harsh chemicals that could harm aquatic life.
