Description
Ultra-Fine Nano Bubbles: Produces incredibly dense micro bubbles that create a gentle mist-like effect in your aquarium. These fine bubbles stay suspended in water longer, significantly improving oxygen dissolution efficiency and water circulation. Perfect for betta, goldfish, shrimp, cichlid, and planted tanks.
Upgraded Fiber Core and Noise Reduction: Unlike traditional sintered air stones, our air stone uses high-density fiber cotton nano material. This upgraded design delivers more uniform airflow and resists clogging much longer. Unlike noisy air stones that disturb your fish and your. The dense nano pore structure naturally reduces noise and vibration.
Safe Material and Self-Sinking Design: Made from premium ABS material, safe for both freshwater and saltwater aquariums. The weighted disc automatically sinks to the bottom and stays firmly in place, no floating, no drifting. This ensures stable positioning and even bubble distribution across the entire surface.
Easy Setup: Soak the air stone in water for 30 mins before first use. Connect to a required air pump(air pump not included), then gently plug and unplug the air tubing 6–10 times to release trapped air and achieve finer, more even bubbles. 3 sizes available: 2.36 Inch (10-30gal), 3.15 Inch (20-50gal), 3.94 Inch (40-100gal).
Complete Kit: Includes 1 x nano bubble air stone, 2 x transparent suction cups, 1 x air tubing, 1 x check valve, 1 x airflow control valve, and 1 x user manual. Designed for convenient installation and compatibility with standard aquarium air pumps. (Air pump not included.) Recommended air pump power: ≥ 3W for 2.36 Inch, ≥ 5W for 3.15 Inch, ≥ 5W for 3.94 Inch.
