Highly Concentrated Magnesium

Fauna Marin Elementals Mg is a highly concentrated magnesium solution for compensating magnesium deficiencies in reef aquariums. It is used primarily by red calcareous algae and soft corals. We recommend maintaining Mg between 1300–1350 mg/L (at 35 salinity) and checking Mg content regularly by a water test.

Always keep it closed after opening. Store dark at room temperature.
