Reef Fusion 1 and reef Fusion 2 are the foundation of a system formulated to provide the essentials for the reef aquarium. Reef Fusion 1 provides calcium, while reef Fusion 2 provides alkalinity. When used together, the reef Fusion system will maintain calcium and alkalinity levels. Reef Fusion 1 provides not only 100, 000 mg/L of ionic calcium, but also includes Biologically Appropriate levels of magnesium, strontium, boron, iron, manganese, and molybdenum. Reef Fusion 2 contains a mixture of carbonates and bicarbonates at an alkalinity of 4400 meq/L. It is designed to restore and maintain alkalinity in the reef aquarium and provide calcareous species with the essential carbonate needed for growth. When used as directed, reef Fusion 1 and reef Fusion 2 will maintain the critical levels of calcium and alkalinity necessary for healthy coral growth, while providing Biologically Appropriate levels of other elements and trace minerals.
