Seachem Reef Fusion 1 5.3gal (1201) *Special Order* is a concentrated calcium supplement for reef aquariums. It is used as the calcium component of Seachem’s two-part Reef Fusion system, helping aquarists maintain the calcium level corals need for ongoing growth. In practical use, Reef Fusion 1 is added separately from its matching alkalinity component (Reef Fusion 2) and is dosed based on aquarium testing and the manufacturer’s directions to support stable reef water chemistry.
