The high-tech external canister filters generation with priming support and full of innovative technology for aquarium sizes up to 600 l. EHEIM professionel II is continuing the philosophy of the professionel series consistently and offers greater efficiency with even more convenience. The large priming cylinder on the pump head is not only a special design element. The filter system is filled with this convenient priming support at "the push of a button" and immediately the system starts working. Complicated priming principles for which every aquarium owner developed his own more or less inconvenient and often also wet technology are now a thing of the past.
