4/6mm Tube 2.5m

I’ve had airline tubing before that was too stiff to bend around the filter, but this one is flexible enough to route neatly behind the tank. The 2.5m length gave me plenty of extra for a loop and even reached my second aquarium.

Finally, tubing that doesn’t kink when I bend it around the tank’s corner—the 4/6mm size fits my air pump’s nozzle perfectly. The 2.5m roll gave me just enough slack to hide the line behind the stand, and it stayed clear after a month of use.

The 2.5-meter length was exactly what I needed to reach from my air pump to the filter, and the tube fits snugly without any leaks. It's pliable enough to bend around the tank's corner without kinking, which made setup super easy.
