EHEIM SUBSTRATpro+ O₂xygen 730g ≈ 1l filter media

The EHEIM SUBSTRATpro+O2xygen is a groundbreaking filter medium that transforms biological water treatment. This innovative product, built upon the reliable SUBSTRATpro, merges top-quality materials with cutting-edge technology. The remarkable effectiveness of EHEIM SUBSTRATpro+O2xygen is attributed to the inclusion of the gemstone mineral tourmaline. Its unique pyroelectric properties generate electron-activated oxygen (super oxygen O2-) when it comes into contact with water, enhancing the oxygen supply within the filter substrate and creating optimal conditions for filter bacteria. This process accelerates metabolic activities in your aquarium and boosts the vitality of fish, plants, and the overall aquatic ecosystem.

Efficiently eliminating pollutants, the spherical structure of this medium allows for a high bulk density, maximizing the use of available filter space. With a porosity of 45%, the ceramic material offers a vast surface area for beneficial microorganisms. The combination of a large colonization surface and activated oxygen facilitates faster, more effective breakdown of pollutants, resulting in crystal-clear water and a thriving ecosystem.

Durable and sustainable, this filter material is specially heat-treated at temperatures exceeding 1,000 °C, ensuring exceptional stability and longevity. It is pH-neutral, reusable, and suitable for both fresh and saltwater environments.
