EHEIM SUBSTRATpro+ O₂xygen 183g ≈ 250ml filter media

The EHEIM SUBSTRATpro+O2xygen is a groundbreaking filter medium that transforms biological water treatment. This innovative product builds on the well-established SUBSTRATpro, integrating high-quality materials with cutting-edge technology. The key to the remarkable performance of EHEIM SUBSTRATpro+O2xygen is the inclusion of the gemstone mineral tourmaline. Its distinct pyroelectric characteristics produce electron-activated oxygen (super oxygen O2-) when it comes into contact with water, enhancing the oxygen supply within the filter substrate and fostering optimal conditions for beneficial filter bacteria. This process boosts metabolic activities in the aquarium, invigorating the health of fish, plants, and the overall aquatic ecosystem. Efficient pollutant removal is achieved through its spherical structure, which allows for a high bulk density and maximizes the use of available filter space. With a porosity of 45%, the ceramic material offers an extensive surface area for beneficial microorganisms. The synergy of a large colonization area and activated oxygen leads to faster, more effective breakdown of pollutants, resulting in crystal-clear water and a thriving ecosystem. Built to last and designed for sustainability, the filter medium undergoes a special heat treatment at temperatures exceeding 1,000 °C, ensuring remarkable stability and durability while providing excellent resistance. It is pH-neutral, reusable, and suitable for both fresh and saltwater environments. Advantages of the EHEIM SUBSTRATpro+O2xygen:
