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 2ï 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.

Sizes: 500 mL, 1 L, 2 L, 4 L

Reef Fusion is different from our other calcium and carbonate supplements in that Reef Fusion 1 & 2 are specifically designed to be used together in a simple 1:1 ratio. There are similar products on the market, but the Reef Fusion system is the most concentrated two part system for maintaining calcium and carbonate alkalinity available.
