KENJI KOI Air Stone Ball
KENJI KOI Air Stone Sphere
Improved Oxygen Supply for Your Pond or Aquarium
KENJI KOI Air Stone Spheres ensure optimal aeration in your pond or aquarium. The spheres, in conjunction with a manifold, allow the pond to be aerated at several points simultaneously.
High-Quality Spheres - No Deterioration After One Year
The spheres are not only corrosion-free but also shock-resistant, allowing the aerators to withstand many stresses. Their high resistance is due to a unique production process – the air stones are hardened in an oven at 1300°C. In this context, it should be noted that the air stones are extremely fine-pored and thus optimally fulfill their function as aerators.
