50mm Air Stone Bubble Diffuser, Nano Air Stone for Aquarium Fish Tank, Fine Tiny Bubbles Maker for Pond, Aquarium and Hydroponics

【Optimal Tank Compatibility】This air stone features a 50mm nano bubble design, perfect for 20-80CM fish tanks when placed below the water surface (air pump and accessories not included).

【Enhanced Oxygen Transfer】The bubble diffuser releases smaller, denser bubbles that boost water oxygen dissolution while reducing carbon dioxide, creating healthier conditions for your aquatic life.

【Whisper-Quiet Operation】Enjoy ultra-low noise performance that won't disturb fish, shrimp, or your household—ideal for bedrooms or living spaces near the tank.

【Adjustable Bubble Control】Easily modify bubble size by hand and achieve instant refining effect once connected to compatible air pump systems, offering customizable aeration.

【Stable & Simple Setup】This air stone stays firmly in place without shifting; for best results, soak in tank water for 2 hours before first use to ensure optimal performance.
