Natural iron-active tropical laterite Duplarit K is the same material as Duplarit G. The ball form makes it easy to bring the natural plant substrate of the tropics into established aquariums. Furthermore, the growth of individual plant groups may be especially promoted by just pressing the balls into the aquarium gravel near the root area. Utilisation of Duplarit K: Duplarit K is used where Duplarit G granules have not been utilised in the initial setting up of the aquarium, or when a selective fertilisation of special plants or plant groups is desired. Just press the balls into the root area of the corresponding plants. The balls should be inserted at least 1 cm under the substrate.
