Hobby Air Vent- Cylindrical, 50 x 18mm

The Dupla Cylinder is an air stone, which serves the oxygen supply in fresh or saltwater aquarium and is available in different sizes.

There is no life without oxygen, that's especially true in the aquarium. Some circumstances call for additional ventilation, such as medication or even rising summer temperatures, as the water heats up and increases in oxygen demand.

The Dupla air vent cylinder-shaped consists of press-glued material and serves to supply oxygen to the aquarium. Due to its round shape, it can also be ideally operated with foam filters. The blue air stone can be connected with a 4/6 mm air hose directly to the air pump and supplies the aquarium water with very fine oxygen beads.

The delivery includes two air stones.
