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

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.

No recomiendo
Format: Paperback
Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.
