EHEIM SUBSTRATpro+O2xygen - A filtration medium that revolutionizes biological water treatment. This latest development, based on the tried and tested SUBSTRATpro, combines high-quality materials with advanced technology.

The secret behind the exceptional effect of EHEIM SUBSTRATpro+O2xygen lies in the tourmaline mineral it contains. Thanks to its unique thermoelectric properties, it generates electronically active oxygen (super oxygen O2-) upon contact with water, enhancing oxygen supply in the filtration medium and creating ideal conditions for filtration bacteria. This stimulates metabolic processes in the aquarium and activates the vitality of fish, plants, and the entire aquatic ecosystem. Effective pollutant removal - the spherical structure allows for high volume density and achieves optimal use of the available filtration space. With a porosity of 45%, the ceramic material provides a large surface area for beneficial microbes. It combines a large colonization surface with active oxygen, contributing to faster and more efficient pollutant breakdown - for clear, healthy water and a thriving ecosystem.

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