Sinking inner tube for pond Ø 4 mm 5 m length

This new innovative sinking inner tube can be easily installed on the pond bottom, without any additional costly fixing or extra ballast respectively. This black inner tube has been especially designed for a clean and inobtrusive installation on bottom of the pond. The heavy and exceptionally solid tube, made of a material based on PVC, is extremely robust, UV-resistant and prevents tangles or cracking. The tube of 5 m in length and a diameter of Ø 4 mm is simply placed in the pond and connected to the air stone balls or plates. TIP: An installation within the pond is sufficient. If there is a need, the connection can be thereafter completed to the air pump by means of a conventional air hose.
