The EHEIM SUBSTRATpro+O2xygen is a groundbreaking filter medium that transforms biological water treatment. This innovative product, built upon the reliable SUBSTRATpro, merges top-quality materials with cutting-edge technology. The remarkable effectiveness of EHEIM SUBSTRATpro+O2xygen is attributed to the inclusion of the gemstone mineral tourmaline. Its unique pyroelectric properties generate electron-activated oxygen (super oxygen O2-) when it comes into contact with water, enhancing the oxygen supply within the filter substrate and creating optimal conditions for filter bacteria. This process accelerates metabolic activities in your aquarium and boosts the vitality of fish, plants, and the overall aquatic ecosystem.

Efficiently eliminating pollutants, the spherical structure of this medium allows for a high bulk density, maximizing the use of available filter space. With a porosity of 45%, the ceramic material offers a vast surface area for beneficial microorganisms. The combination of a large colonization surface and activated oxygen facilitates faster, more effective breakdown of pollutants, resulting in crystal-clear water and a thriving ecosystem.

Durable and sustainable, this filter material is specially heat-treated at temperatures exceeding 1,000 °C, ensuring exceptional stability and longevity. It is pH-neutral, reusable, and suitable for both fresh 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 and healthy aquarium environment
  • Fast degradation of pollutants: allows for extremely rapid biological breakdown of impurities
  • Promotion of metabolism: activated oxygen enhances the health of fish, plants, and the entire ecosystem
  • Durable and robust: fired at extreme temperatures (over 1,000°C), the material offers remarkable durability
  • Reusable: can be cleaned by rinsing carefully
  • Suitable for fresh and salt water

Beautiful, Versatile Boot
Size: 8.5, Color: Cyprus Tan
Versatile boots for business wear. The calf profile is sleek and slim so they are wearable under straight cut pants but also look beautiful paired with a midi skirt and sweater. I am 5’6” and 145 lbs. These stop right below my kneecap and have just enough room in the calf to slide up my leg but stay in place. I am usually a size 8 and originally purchased an 8 in these boots but found the toe too short and narrow. When I sized up to an 8.5 the toe bed was comfortable and roomy. Heel is just high enough to give a dressed up look but is still comfortable to walk in.

I make sure to condition the leather on my boots before wearing and after every 2nd to 3rd wearing stuff the bootsto store them.

Buttery soft, comfortable and the perfect height!!!
Size: 10.5, Color: Black Leather, Size: 10.5, Color: Black Leather
I ripped these out of the box as soon as they arrived lol 😂 I knew they were the black knee high boots that I wanted to have as a staple in my Fall closet. They did not disappoint! The stitching is impeccable, they are buttery soft from top to bottom, they are the signature San Edelman design, the heel is perfect – it’s not clunky it’s sleek, but it’s not too high so you can wear these with pants and dresses and skirts. They are VERY COMFORTABLE!!! They are pointy - but I sized up a half so they are not squeezing my foot at all. I can move my toes around and there’s enough space for socks if I need to wear them. I am in ❤️!!!
