Multi-Size Aquarium LED Bubble Bar with Light, USB Color-Changing

Aquarium LED Bubble Light, USB Color-Changing Submersible Light Bar with Suction Cups for Small Fish Tanks, Air Pump Required and Not Included

Turn a Plain Bubble Line into a Color-Changing Aquarium Feature

Add movement and color to a small aquarium with one compact 6,10,14-inch bar. USB power illuminates the sealed underwater light, while a separately connected air pump sends bubbles through the diffuser to create a colorful bubble-wall effect.

Why It Stands Out

• Light and bubble diffuser in one bar: Combining both elements keeps compact tanks cleaner-looking than installing a separate light strip and air stone in the same area.
• Automatic color-changing LEDs: The underwater glow shifts through colors to add visual depth behind fish, plants, and décor without requiring a remote.
• Fine bubble-curtain effect: When connected to an external air pump, the diffuser releases a line of bubbles that adds motion and supports surface agitation.
• Suction-cup positioning: Mount the bar along the tank floor or inner glass and adjust its placement to suit the aquascape.
• Compact for small tanks: The body needs approximately 1.6 inch(4cm) extra of usable internal tank length, making it suitable for desktop aquariums and other space-conscious displays.

How to Use

Place the light bar fully underwater, secure it with the suction cups, connect suitable airline tubing to an external aquarium air pump, and power the light through the specified USB supply. Use a stronger pump when water depth and airline resistance reduce bubble uniformity.
