EHEIM SUBSTRAT 830g ≈ 1l filter media

EHEIM SUBSTRAT Standard bio-filter medium featuring a vast colonization area for beneficial bacteria and exceptional efficiency. SUBSTRAT can be arranged in one or multiple layers. This filter material is highly porous and crafted from sintered glass. Its unique surface structure provides optimal conditions for the essential purification bacteria to thrive. The available colonizable area is an impressive 450 m² per litre. EHEIM SUBSTRAT is washable and can be reused. Standard bio-filter medium Highly porous material made from sintered glass Excellent conditions for bacteria cultures Reusable (rinse gently to clean) The primary function of biological filter media is to create the ideal conditions for bacteria cultures, allowing a thriving bacteria lawn to develop in a short period. These bacteria consume various dirt particles and transform substances that could be harmful to your aquarium. After the initial cleaning phase conducted by mechanical filter media (such as EHEIM MECH or MECHpro), biological filtration becomes crucial. It ensures clear, healthy water and stable water parameters. This is why we have dedicated significant research efforts to the advancement of biological filter media. Tip: Avoid cleaning or replacing all filter media simultaneously (and refrain from overly aggressive cleaning). It's crucial to preserve the bacteria cultures; otherwise, the re-colonization process will be delayed. The filter baskets in external filters and filter modules within internal filters like aquaball and biopower are perfect for partial cleaning.
