The substrate from research on aquatic plants.

The aquatic greenhouses of Dennerle have developed a very specific long -lasting composition mineral substrate for several years of testing: Deponitmix Professional.
Nature served as a model. Fine quality siliceous sand creates an optimal climate in the substrate. Carefully selected clay minerals regulate the nutritive regime. They release nutrients in case of deficiencies and absorb them in the event of excess. Natural peats rich in humines create a slightly acidic environment and disintegrate nutrient substances to make them easily assimilated by plants. Concentrated nutritive iron, combined with vital trace elements, guarantees balanced growth and nourished green leaves. A very porous special granulated tenfold the biofiltrant function, for improved water and healthy fish. DEPONITMIX Professional guarantees safe rooting and vigorous radiation, even with more sensitive species. It does not contain phosphates or nitrates added and therefore does not promote the proliferation of algae.
