Eheim Substrat Pro Filter Media

Brand: Eheim Substrat Pro Filter Media The primary function of biological filter media is to provide optimal conditions for bacterial cultures, quickly creating a bacterial lawn. The bacteria feed on all types of dirt particles and convert the substances critical to the aquarium. After initial cleaning with mechanical filter media (e.g., EHEIM MECH or MECHpro), biological filtration is the most important step. It ensures clear, healthy water and stable water parameters. That's why we've invested extensive research into the development of biological filter media. Optimized bio-filter medium with perfect volume utilization, long service life and highest degradation performance SUBSTRATpro is made of spherically sintered quartz. The spherical shape allows for a high bulk density. This allows the volume in the filter (filter baskets or modules) to be fully utilized. In addition, the optimized surface of the spheres ensures intensive colonization of the important purification bacteria. A dense bacterial growth is formed. The high number of bacteria also effectively reduces nitrite load peaks and extends the service life of the filter material. EHEIM SUBSTRATpro is suitable for freshwater and saltwater, is washable, and can be reused multiple times. Optimized bio-filter medium made of sintered quartz High bulk density due to spherical shape (beads) Very dense bacterial colonization Longer service life Better degradation of nitrite contamination Reusable (rinse carefully to clean) Suitable for fresh and salt water Tip: Never clean or replace the entire biological filter material in one go (and never too thoroughly). The bacterial cultures must not be completely destroyed, as this will delay recolonization. The filter baskets in external filters and the filter modules in the aquaball and biopower internal filters are ideal for partial cleaning.
