The EHEIM Substrat 830g (1L) is a high-performance biological filter medium designed to support crystal-clear, stable, and healthy aquarium water. Made from highly porous sintered glass, this media provides an enormous surface area of 450 m² per litre for beneficial bacteria to colonise. These bacteria play a crucial role in breaking down harmful substances and ensuring long-term water quality.
