This elbow is for aquarists whose CO2 or airpump tubing keeps lifting off the glass or bending at the rim of the tank. It replaces suction cups, which lose grip over time, with a clip that holds the tubing in a fixed route.
Why it matters
- Elastic clip action: The ends are not quite parallel, and the elbow flexes so it can be stretched over the tank wall and grips the glass.
- Glass thickness range: It fits panes from 6mm to 8mm, the range given for this model.
- Acrylic construction: Made of acrylic rather than glass, so it bends without breaking and does not crack when fitted to a thicker or thinner pane.
- Transparent body: The clear material keeps the tubing visually unobtrusive on the tank.

What it works with
The clip suits any freshwater or planted tank that uses a CO2 system or an airpump with 6mm tubing and glass between 6mm and 8mm thick. Because it is compatible with all airpumps and CO2 setups listed for this model, it can be used across different equipment in the same aquarium.
