Dupla is a German company that has revolutionized the system of "thinking aquariums" in Germany. Dupla was the first to propose the open aquarium, the percolating filter with a strong current flow in the water, intense lighting. In practice, it brought the conditions of tropical rivers into the aquarium. Thanks to a book, The Optimum Aquarium, he introduced the concepts that have been milestones for aquariology. Injection of CO2, lighting, filtering, control of the chemical values of the water, use of the best products for the care and nutrition of plants and fish, "simple" concepts with which certain successes would have been achieved. Thus was born Duplarin, the first granulated feed, Duplabacter, Duplagan, Duplaplant, names that any aquarist then and now associates with the concept of the optimal aquarium. In 2004 it became part of Dohse Aquaristik and has since then developed further in the marine sector by introducing the Duplamarin logo.
Aquaristica was born in 1986 to introduce the optimal Dupla aquarium in Italy. Aquaristica has always been the exclusive distributor of Dupla.
