Dupla Duplarit K

Duplarit K is an iron-active tropical laterite in the form of a ball for fertilising the substrate in freshwater aquariums to be set up.

Duplarit K is a natural iron-active tropical laterite in the shape of a ball for new aquariums and serves as substrate fertiliser for all aquarium plants. Duplarit K promotes growth and appearance and prevents deficiency symptoms. It also contains soil bacteria that develop nutrients in symbiosis with the roots. The balls have a diameter of approx. 25 mm and can simply be pressed into the ground at the roots. Duplarit K can be combined excellently with other types of fertiliser!
