EHEIM SUBSTRATpro+ O₂xygen 183g ≈ 250ml filter mediaThe 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 )
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:- High-quality material: ceramic filter mass made from silicates and tourmaline
- Innovative technology: Tourmaline generates electron-activated oxygen (super oxygen O2-) for effective oxygen supply
- High porosity of 45%: provides an above-average settlement area for filter bacteria
- pH-neutral: maintains water chemistry stability for a healthy aquarium environment
- Fast degradation of pollutants: enables rapid biological breakdown of impurities
- Promotion of metabolism: Activated oxygen enhances the vitality of fish, plants, and the entire ecosystem
- Durable and robust: The material is fired at extreme heat (over 1,000 °C), ensuring outstanding durability
- Reusable: Can be cleaned and used multiple times (rinse carefully)
- Suitable for fresh and saltwater: Versatile for various aquatic environments

Good quality
Color: Crisp White, Size: Medium
Fit is great, feels like a durable material. Generally a very nice shirt! Bought this for a 5’ 10” male who is 150lbs. Medium was just right, with a little bit of breathing room.

Good for an emergency only
Color: Crisp White, Size: X-Large
Shirts are good overall, but the material is too light ... if you are hairy or have dark skin, you need an undershirt; otherwise, it looks like the shirt is dirty.

Excellent style and quality for price
Color: Grey Blue, Size: Medium
Very nice quality and affordable price. Fabric is soft and smooth, very few wrinkles after washing and drying and easy to iron. Seems durable for machine washing and drying. Fits true to size.
