The EHEIM SUBSTRATpro+O2xygen - a filter medium that revolutionises biological water treatment. This latest development, based on the tried and tested SUBSTRATpro, combines first-class materials with stateof-the-art technology. The secret behind the extraordinary effect of EHEIM SUBSTRATpro+O2xygen lies in the gemstone mineral tourmaline it contains. Thanks to its unique pyroelectric properties, it generates electron-activated oxygen (super oxygen O2-) on contact with water, which optimises the oxygen supply in the filter substrate and creates ideal conditions for filter bacteria. This stimulates the metabolic processes in the aquarium and activates the vitality of fish, plants and the entire aquatic ecosystem. Efficient removal of pollutants - the spherical structure enables a high bulk density and makes optimum use of the available filter space. With a porosity of 45 %, the ceramic material provides a huge surface area for beneficial microorganisms. The combination of a large colonisation surface and activated oxygen breaks down pollutants faster and more efficiently - for crystal-clear water and a healthy ecosystem. Durable & sustainable - the filter material is specially heattreated at over 1,000 °C, which makes it particularly stable and durable and guarantees outstanding resistance. It is pHneutral, reusable and suitable for fresh and salt water. Advantages of the EHEIM SUBSTRATpro+O2xygen High-quality material: ceramic filter mass made of sili-cates and tourmaline Innovative technology: Tourmaline produces electronactivated oxygen (super oxygen O2-) for efficient oxygen supply High porosity of 45%: for an above-average settlement area of filter bacteria pH-neutral: Does not affect the water chemistry and ensures a stable, healthy aquarium climate Fast degradation of pollutants: Allows extremely fast biological degradation of impurities Promotion of metabolism: Activated oxygen strengthens fish, plants and the entire ecosystem Durable and robust: Burned by extreme heat (over 1.000°C), the mate-rial offers exceptional durability Can be used several times (rinse carefully for cleaning) Suitable for fresh and sea water
