## Long description

ZOLUX aerator model 321322 is a compact mechanical air diffuser with a 40 mm diameter and 15 mm height designed to introduce air into aquarium and pond water. Its small footprint and simple construction make it suitable for local oxygenation and improving circulation in small tanks, breeding setups and focused treatment zones. The aerator supports oxygen transfer at contact points with water and contributes to overall water quality when used with appropriate air pumps and filtration systems.
Advantages
The aerator's compact round shape and shallow profile allow installation in confined spaces without obstructing decor or equipment. Its mechanical design provides steady air dispersion to increase dissolved oxygen levels near the diffuser. The product is made for easy integration with standard aquarium tubing and air pumps and can be positioned close to substrate or plant areas to support biological filtration and fish welfare.
Suitable for
 Small aquariums and desktop tanks
 Breeding or fry rearing setups requiring localized aeration
 Supplemental oxygenation in ponds or garden water features at circulation points
 Supporting biological filtration by increasing water movement near filters and substrates
Key specifications
 Shape and size: circular diffuser, 40 mm diameter, 15 mm height
 Material: durable, water-resistant components suitable for aquatic use
 Connection type: compatible with standard aquarium air tubing
 Installation: surface-placed or fixed at local points for targeted aeration
 Use environment: freshwater and garden pond applications
How to use
Connect the aerator to a suitably sized air pump using standard aquarium tubing and place it where additional oxygenation is needed. Ensure the air pump provides appropriate flow for tank size so the diffuser produces steady bubbles without excessive turbulence. Position the unit near substrate, plants or filter inlets to promote localized circulation and improved gas exchange. Periodically check tubing and connections for wear and clean the diffuser if mineral deposits or biofilm reduce airflow.
Usage recommendations
For reliable performance use an air pump rated for the volume of your aquarium or pond and consider adding an adjustable valve or check valve to control airflow. Clean the aerator gently with water and a soft brush; avoid harsh chemicals that can harm fish and plants. In planted tanks, balance aeration with CO2 dosing schedules to maintain stable conditions.
