The available starting water does not always offer ideal conditions for the care of demanding animals and plants in the aquarium. In addition, in the retracted saltwater aquarium, alkaline earth metals and valuable trace elements can quickly be used up through chemical processes, precipitation and installation in limestone skeletons. To (re) establish stable, natural conditions, Tropic Marin® offers all the necessary minerals and trace elements required for the (re-)establishment of stable, true-to-nature conditions in the aquarium. Create true-to-nature water conditions that your aquarium dwellers are used to.
