What is Dupla?

Dupla factory

Dupla Aquaristik GmbH – Bielefeld – Germany

The company Dupla Aquaristik GmbH was formed in 1978 by Horst Kipper. A hobbyist from boyhood, Horst Kipper spent the early years with Eheim and then Tetra, but decided to establish his own company where he could fully develop his ideas and turn these into exclusive and effective aquarium systems that would assist the average aquarist to achieve outstanding success in the aquarium. Together with his long-time friend and associate Kaspar Horst, EDTA, CO2, fertilisation, specific lighting, substrate, heating, etc. were developed.

Long before any environment and animal protectors campaigned for proper treatment of pets, the foreword of the Dupla Exclusive Contract for aquarium shops stated:

“Dupla and its partners commit to do what they can for the progressive protection of nature, animals and the environment; further, to observe any and all laws related to nature and animal protection and to conduct their business in an exemplary manner.”

In 1983 Kaspar Horst became Managing Director of Dupla Aquaristik GmbH, so that Horst Kipper could establish in Australia, a research facility for freshwater and marine aquaristics. This culminated in the building of Dupla Tropica, situated on the edge of the rain forest and a short distance from the sea in the Cairns region of Australia. From there, significant further contribution was made to the Dupla product line and the science of aquaristics in general.

In 1998 Jörg Plöger assumed the position of Managing Director, enabling Kaspar Horst to concentrate on his long-term profession, as editor and publisher of Aquarium Heute.

Dohse Aquaristik KG – Grafschaft, Germany

In October 2003 the well-respected firm Dohse Aquaristik KG acquired the national and international rights and products of Dupla. This enabled the important next step for the development and strengthening of the Dupla product line.  Dohse Aquaristik KG is a long-established family business that has been successfully producing aquarium products since its formation in 1949. With over 65 years experience in the aquaristic industry producing the HOBBY line, now the DUPLA line – itself with over 36 years history – is added to this solid foundation and continues as an independent range. Jörg Plöger was also appointed as Sales Manager, therefore facilitating continuity of this benchmark line.

Dohse Aquaristik KG is now in its third generation under the control of its Managing Director – Axel Pinders. Although there are many new developments in progress, some things will not change. Established and proven products will not be altered, and original formulations are retained except where a distinct improvement can be demonstrated. The optimisation of the living conditions of fish and the handling security for the aquarist remain the main goal against which, all activities are measured.
