Ultra-fine nano bubbles with 150 mm length design create dense, oxygen-rich bubbles for higher oxygen dissolution, supporting healthier fish and plants. Durable and flexible material built from non-toxic, corrosion-resistant polymer. Safe for both freshwater and saltwater tanks and compatible with most air pumps (3-10 W recommended). Quiet operation and easy installation with low-noise performance that won’t disturb aquatic life. Includes suction cups and connectors for quick setup in any tank shape. Enhanced water circulation through uniform bubble distribution that prevents dead zones, promoting a balanced ecosystem and crystal-clear water quality. Use scenarios - Planted freshwater tanks: improves oxygenation and circulation to support plant health and vibrant growth. - Breeding or fry tanks: steady, gentle aeration helps maintain oxygen levels without stressing delicate residents. - Mixed or saltwater tanks: safe for diverse tank types, delivering reliable aeration and improved water quality without noise or mess.
