Add reliable aeration and a striking bubble wall to your tank with this flexible aquarium air curtain. Designed to create a curtain of fine bubbles along its length, it helps improve oxygen exchange and water movement while adding a clean visual line that suits planted, tropical and marine displays. Choose from blue or green to match your setup and six lengths to fit nano to larger aquariums.

Installation is quick: connect standard aquarium airline to your air pump (not included), position the diffuser where you want the bubble wall, and press the included suction cups onto clean glass. The flexible body lets you run it straight across the back, curve it around hardscape, or place it low for a lifting current that helps reduce dead spots. Fine perforations distribute bubbles more evenly, while the slim profile keeps attention on fish and aquascape.

Easy to maintain, the tube can be lifted for a rinse if bubbles become uneven; a brief soak in dechlorinated water helps clear mineral build-up. Whether you’re boosting oxygen for warm Aussie summers, improving circulation after feeding, or adding a subtle visual feature, this air curtain is a practical, low-cost upgrade for everyday aquarium care.
