Expertise for Aquariums and Technology EHEIM technology: the basis of fishkeeping As pioneers for modern aquarium technology EHEIM have maintained their globally leading position for decades. As in the past, innovative developments set standards in the field of quality filter systems, technical installations and a sensible range of accessories. This technology copies the natural habitats in the aquarium and turns garden ponds into living biotopes on a small scale. Typical habitats for the spectrum of species are our prime objective at all times. FROM TOYS TO TECHNOLOGY The company Gunther Eheim founded in 1949 gained fame as a successful producer of technical toys. Even in those days a specially developed centrifugal pump was part of the programme as an accessory for model trains. Later the prototype of the first aquarium filter was based on this technology.
