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

Not paper thin like most T-Shirts
Color: Light Khaki, Size: X-Large
These Cooney tshirts are really nice. Feel like 100% cotton and keep their shape and color. Size true to fit. Good value for the money. Love the mock neck style. Bot a couple one in white and one in black. Then went back and ordered 6 more various colors. Like the all.
