DuplaRin and DuplaRin Mar are unique food concepts that were developed together with leading scientists over many years of research and trials. An exceptionally gentle production process ensures full preservation of the carefully selected vitamins, proteins and trace elements to meet the natural and special requirements of marine fish. Not only fish need food, corals do as well. Although most stony corals hosting zooxanthellae mainly feed on the metabolism of the symbiotic algae, which can also cover almost 90 percent of the energy requirement in optimum conditions, research has shown that nitrogen compounds, amino acids, vitamins and organic compounds are necessary for this metabolism and coral growth. Since the corals hosting zooxanthellae are not able to produce sufficient amounts, if any, of these substances, the coral must cover this requirement by means of active nutrient uptake through polyps. DuplaRin Coral Food and DuplaRin Coral Food phyto is a floating food and plankton substitute that corresponds to the nutritional needs of these food specialists.
