EHEIM Bio Mech 2 Litre Mechanical-biological filter medium for combined water treatment bioMECH has been cleverly designed: dirt-trapping pockets capture and retain large and small dirt particles. At the same time the subtly designed pore structure provides colonization for the purification bacteria and thus ensures reliable biological decomposition. The material is pH-neutral and does not contain water hardeners. EHEIM bioMECH is suitable for fresh and marine water, is washable and reusable many times. Specially designed filter medium for simultaneous mechanical and biological water purification. The material is pH-neutral and without water hardeners. Reusable (wash out carefully, in order not to destroy the bacteria cultures). Suitable for fresh and marine water.
