Fauna Marin Elementals Mg 1000ml T_AquariumFilter Virtually free from dust andMagnesium is an essential element that helps maintain calcium and carbonate concentrations in aquarium water. It is used primarily by red calcareous algae and soft corals. When available in the correct concentration, coral calcification rates improve. We recommend maintaining Mg between 1300 1350 mg L (at 35 salinity) and checking Mg content regularly by a water test.
