Eheim Filter Media

Eheim filter media - highly efficient, developed in Eheim's own laboratory, produced from only the best raw materials, continuously checked and guaranteed free from pollutants.

  • To adsorb means to take up onto a surface (as opposed to absorb = to take in). Adsorptive filter media are thus materials, which extract harmful substances from the water and attach or retain them. These substances are, for instance, chlorine in... more info
  • Biological Filter Media The main task of biological filter media is to offer the best colonisation conditions for the bacteria cultures, so that after a short time a bacteria lawn develops. The bacteria feed on dirt particles of all kind and... more info
  • Depending on which type, chemical filter media control the pH-value and the water hardness (peat) – or reduce the phosphate level and inhibit the growth of algae (phosphateout).
  • Mechanical Filter Media Coarse material works directly where the filtration process begns.  The water is swirled around and larger dirt particles become trapped.  The water then flows through the rest of the filtering process.
