The EHEIM SUBSTRATpro+O2xygen is an innovative filter medium that transforms biological water treatment. This latest version, building upon the well-established SUBSTRATpro, merges premium materials with cutting-edge technology. The remarkable effectiveness of EHEIM SUBSTRATpro+O2xygen is attributed to the gemstone mineral tourmaline it incorporates. Its unique pyroelectric characteristics allow it to generate electron-activated oxygen (super oxygen O2-) upon contact with water, enhancing the oxygen supply within the filter substrate and creating optimal conditions for filter bacteria. This process boosts metabolic activities in the aquarium, enhancing the health of fish, plants, and the entire aquatic ecosystem.

Efficient pollutant removal is achieved thanks to its spherical structure, which allows for 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 combination of ample colonization surface and activated oxygen facilitates quicker and more efficient breakdown of pollutants, resulting in crystal-clear water and a thriving ecosystem.

Durable and sustainable, this filter medium is specially treated at temperatures exceeding 1,000 °C, ensuring exceptional stability and resilience while providing outstanding resistance. It is pH-neutral, reusable, and suitable for both freshwater and saltwater environments.

  • High-quality material: ceramic filter mass made of silicates and tourmaline
  • Innovative technology: Tourmaline produces electron-activated oxygen (super oxygen O2-) for efficient oxygen supply
  • High porosity of 45%: provides an above-average settlement area for filter bacteria
  • pH-neutral: does not affect water chemistry, ensuring a stable, healthy aquarium environment
  • Fast degradation of pollutants: allows for rapid biological breakdown of impurities
  • Promotion of metabolism: activated oxygen boosts the vitality of fish, plants, and the entire ecosystem
  • Durable and robust: treated with extreme heat (over 1,000°C), the material offers exceptional longevity
  • Reusable: can be cleaned and used multiple times
  • Suitable for fresh and saltwater: versatile for various aquatic environments

True to size
Color: Lake Green, Size: Large
Ordered this because my husband has ordered tank tops from this company so I had something for reference, but this ran true to size and fit my husband great. He’s a size L. The shirt had like a dry fit feel to it. It was breathable and was pretty wrinkle resistant. We’ve washed and dried it a few times and it doesn’t get crazy wrinkles. It’s not too thick so it’s great for an occasion during warmer weather. There was a huge variety of different styles of shirts. For the price it’s great.

Stubborn Wrinkles
Color: Black, Size: XX-Large
The shirt came vacuum sealed. After two washings the wrinkles are still there. Beautiful shirt but not wearable yet. I'll try steaming it! It fits well.

Great shirt and Great price

I really like this short sleeve shirt — it’s stylish, comfortable, and perfect for any occasion. The fabric feels soft yet durable, and it keeps me cool even on warmer days. The fit is flattering without being too tight, making it a great addition to my everyday wardrobe.
