## Summary description

ZOLUX mountain-shaped aquarium aerator (model 321323) is an air stone designed to diffuse air into aquarium water.

Suitable for home aquariums, planted tanks and ornamental displays where both function and visual appearance matter.

## Long description

ZOLUX mountain-shaped aquarium aerator model 321323 is a decorative air stone designed to diffuse air into aquarium water to support oxygenation and gentle circulation. The sculpted mountain silhouette integrates into planted tanks and ornamental displays while producing a fine stream of bubbles that increases gas exchange at the water surface and reduces stagnant zones.
Advantages
The mountain-shaped design combines aesthetic integration with functional aeration, offering an unobtrusive decorative element that distributes air evenly through a porous ceramic surface. It promotes steady water movement without strong currents, is compatible with standard aquarium tubing and air pumps, and helps maintain healthier conditions for fish and plants by improving oxygen levels and surface agitation.
Suitable for
 Home freshwater aquariums
 Planted tanks requiring gentle circulation
 Ornamental displays where appearance and aeration are both important
 Environments needing improved surface oxygen exchange
Key specifications
 Form: decorative mountain-shaped air stone
 Function: fine bubble diffusion for aeration and mild circulation
 Compatibility: connects to standard aquarium air tubing and air pumps
 Material: porous diffusion medium suitable for underwater use
 Intended use: freshwater aquarium environments including planted tanks
How to use
Attach the aerator to a compatible air pump using standard aquarium tubing and position the mountain-shaped air stone on the aquarium substrate or a stable decorative area. Ensure the airline is free of kinks and that the pump provides appropriate airflow; adjust pump output or add an in-line valve if necessary to obtain a steady, fine stream of bubbles. Regularly inspect the stone for buildup and clean as needed to maintain diffusion efficiency.
Usage recommendations
For best results, place the air stone away from heavy water flow from filters to allow even bubble distribution. Periodically remove and rinse the aerator under aquarium water or soak in dechlorinated water to reduce clogging from detritus; avoid aggressive scrubbing that could damage the porous surface. Match pump output to aquarium size to prevent excessive current while ensuring effective oxygenation.
