Tropic Marin Carbocalcium is ultra concentrated calcium and carbonate hardness for advanced reef aquarists. With Tropic Marin Carbocalcium, the total calcium and carbonate hardness needs of a typical reef aquarium can be covered with a single solution, without any additional unwanted compounds or excess carbon dioxide being created. Minerals are consumed through the growth of organisms and other processes in the aquarium and must therefore be supplemented regularly. These include mainly calcium and carbonate hardness elements for the growth of the calcareous skeletons of stony corals, red coralline algae and other reef organisms. The special co-ordinated components in Tropic Marin Carbocalcium provide excellent care conditions in only a single solution. Tropic Marin Carbocalcium prevents all the side effects of other methods of calcium hardness: the pH remains stable, there is no excess CO2 and there is no risk of unwanted phosphates being introduced through coral breakage.
