EHEIM SUBSTRATpro+O2xygen - A game-changing filtration medium in biological water treatment. These latest developments, based on the proven SUBSTRATpro, combine top-grade materials with modern technologies.

The secret behind the exceptional effect of EHEIM SUBSTRATpro+O2xygen lies in the gemstone mineral tourmaline it contains. Thanks to its unique pyroelectric properties, it produces electronically activated oxygen (super oxygen O2-) upon contact with water, enhancing oxygen supply in the filtration medium and creating ideal conditions for filter bacteria. This stimulates metabolic processes in the aquarium and boosts the vitality of fish, plants, and the entire aquatic ecosystem. Effective pollutant removal - the spherical structure enables high volume density and maximizes the use of available filtration space. With porosity up to 45%, this ceramic material provides an enormous surface area for beneficial microbes. It combines large colonization space with activated oxygen, aiding in faster and more efficient pollutant breakdown - for crystal-clear water and a healthy ecosystem.

Durable and sustainable - The filtration material is specially heat-treated at temperatures exceeding 1000°C, making it particularly stable and durable, ensuring exceptional resistance. It is pH neutral, reusable, and suitable for both freshwater and saltwater.
