## Summary description

ZOLUX air stone in a 2 cm spherical shape (model 30177) is an aquarium aeration accessory designed to diffuse air into water to improve oxygenation and circulation. Suitable for small tanks, ornaments, or as part of an air pump system; it produces fine bubbles to support fish respiration, reduce stagnant zones and enhance filtration efficiency.

## Long description

ZOLUX air stone 2 cm sphere (model 30177) is an aquarium aeration accessory designed to diffuse air into water for improved oxygenation and circulation. The compact spherical diffuser produces a steady stream of fine bubbles that helps maintain dissolved oxygen levels, reduces stagnation in small tanks and decorative setups, and supports the mechanical and biological functions of filters. Its small size makes it suitable for confined spaces, planted tanks with low flow or ornament integration where discreet aeration is required.
Advantages
The spherical design generates a uniform distribution of fine bubbles, promoting efficient gas exchange without creating strong currents that could disturb sensitive species or plants. The accessory is easy to position and integrates with standard airline tubing and air pumps; its small diameter allows placement behind rocks, ornaments or inside filter chambers. Made for consistent performance in small-scale aquaria, it contributes to clearer water and more stable aquarium conditions when used as part of an aeration system.
Suitable for
Small freshwater aquariums and nano tanks
Ornamental displays and decorative rock or plant arrangements
Supplementing air pumps and in-line aeration systems
Improving oxygenation near filter inlets and low-flow areas
Key specifications
Shape: spherical diffuser
Diameter: 2 cm
Bubble type: fine bubble diffusion for improved gas exchange
Material: durable porous aeration medium designed for water use
Connection: compatible with standard aquarium airline tubing
How to use
Attach the airline tubing from the air pump to the diffuser, prime the pump as recommended by its manufacturer, and place the air stone at the desired location in the aquarium. Positioning near the bottom or behind decor will allow bubbles to rise through the water column and increase circulation without creating excessive flow. Periodically verify airflow and reposition if necessary to achieve even bubble distribution. Replace the diffuser if clogging or significantly reduced output is observed.
Usage recommendations
For best results use an appropriately sized air pump with a flow rate suitable for small aquaria, and consider adding a check valve to prevent backflow. Clean the diffuser by gently brushing or soaking in a mild bleach solution followed by thorough rinsing if mineral buildup reduces performance; allow it to dry fully before returning to the aquarium. Regular inspection ensures continuous oxygenation and helps maintain stable tank conditions.
