Seachem Reef Fusion 1 and Reef Fusion 2 are the foundation of a system formulated to provide the essentials for a reef aquarium. You should purchase Seachem Reef Fusion 2 to use in conjunction with Reef Fusion 1. Reef Fusion 1 provides calcium, while Reef Fusion 2 provides alkalinity. 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.
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 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. Dose aquarium every 1-2 days. Add 1 ml of Reef Fusion 1 per 6.5 US gallons of water. Add Reef Fusion 2 in the same manner.
