Product Description

This cylindrical airstone diffuser is designed to improve dissolved oxygen (DO) levels in water, reduce stress in fish, and enhance biological filtration. The brass nozzle ensures a secure and durable connection to your airline, preventing leaks and extending the service life of the stone.

By producing fine, evenly distributed bubbles, this airstone improves water circulation, prevents stagnant zones, and creates a healthier aquatic environment for koi, shrimp, ornamental fish, and plants.

• Soak the airstone in water for 1 hour before first use.
• Connect airline tubing securely to the brass nozzle.
• Pair with an air pump of suitable capacity (≥15W recommended).
• Place the airstone at the desired depth in your pond or aquarium.
• For best performance, clean periodically with a brush to remove debris.

Why Choose This Cylindrical Airstone?

Compared to regular plastic diffusers, this brass-nozzle airstone provides:
✔ Stronger durability and resistance to wear.
✔ Consistent bubble size for efficient aeration.
✔ Longer service life with lower clogging risk.
✔ Versatility for both small aquariums and large aquaculture ponds.
