YauBay Air Curtain

The YauBay Air Curtain is a flexible air diffuser designed to produce a continuous wall of fine bubbles across the width of your aquarium. It improves oxygen exchange and water circulation, and adds a clean, striking visual effect to freshwater and marine setups alike. Available in two sizes to suit tanks of different scale.

How It Works

Connected to a standard air pump, the air curtain distributes airflow evenly along its length, pushing a uniform curtain of bubbles from substrate to surface. This promotes gas exchange at the water's surface and helps keep water movement consistent throughout the tank.

Compatible With Freshwater and Marine Tanks

The YauBay Air Curtain works across a wide range of setups — tropical community tanks, planted aquariums, and marine systems. Its flexible construction allows it to sit flush along the base of the aquarium without curling or lifting.

Simple to Install

Attaches to any standard air pump via airline tubing. No specialist fittings or tools are required. Lay it along the back or side of the substrate and connect — it is straightforward to set up whether you are adding aeration to an existing tank or building a new one.
