Multimineral nutrient soil for freshwater aquaria

Based on arguably the best culture medium in the world – Deponit-Mix Professional – we have developed a black version that is almost unnoticeable under or on dark gravel. Except for the white activator beads, Deponit-Mix Black has the same excellent performance as its lighter colored sister product.

Building on its extensive knowledge of the natural habitats of the most popular aquatic plants, Dennerle has developed a humus-rich long-term mineral nutrient soil especially for aquariums. The plant is optimally supplied with all the nutrients it needs via the strong, widely branched rootstock. This allows the care of even sensitive species that are rather difficult to keep in the aquarium. Of course, Deponit-Mix does not contain any additional phosphates and nitrates – nutrients that can promote algae in excessive concentrations – and it is covered by the aquarium gravel as the bottom layer. Many years of practical experience show: Deponit-Mix effectively prevents algae plagues. The combination of depot nutrients, trace elements and clay minerals, which regulate the nutrient balance, always gives the aquatic plant roots the right amount of nutrients. Humic-rich natural peat slightly acidifies the soil and makes plant nutrients more available. Clay minerals, humus substances and soil bacteria are already active in the slightly moistened deponite mix. The bacteria are supplied with oxygen through the two holes in the lid. Also unique are the white activator beads, which provide full microorganism power right at the start like a bacterial filling station. Depending on the plant population, lighting and other fertilization, aquariums with Deponit-Mix can last up to 10 years.
