Ultra-Fine Nano Bubbles for Silent Oxygenation：4 inch fish tank bubbler air stone uses advanced sintered ceramic to produce ultra-fine, mist-like bubbles that maximize oxygen dissolution. Enjoy powerful aeration with minimal noise—perfect for peaceful betta tanks and sensitive shrimp aquariums.
Durable Sintered Ceramic & ABS Construction：Built to last, this aquarium air stone features high-temperature sintered ceramic and a reinforced ABS frame. Resists cracking, clogging, acid, and alkali—ideal for long-term use in both freshwater and saltwater fish tanks.
Complete Kit for Easy Setup：Everything you need in one box: 1x 3.2" nano airstone, air tube, regulator valve, Y-connector, check valve, and 2 suction cups. This full accessory kit makes it the most convenient aquarium bubbler to install—no extra parts needed.
Perfect Fit for Small to Medium Tanks：At 4 inches (100mm), this air stone for aquarium perfectly fits medium-sized tanks. Whether you have a community tank, planted aquarium, or reef setup, it delivers even bubble distribution and excellent water circulation for optimal aquatic health.
Soak 1–2 Hours for Instant Bubbling:For best performance, soak the airstone in water for 1–2 hours before first use (tilt at 45° with inlet up). This removes trapped air and ensures immediate, uniform bubble flow—making it the fastest-starting air stone for aquarium fish tank setups.
