We include a 50 ml (2 fl. oz.) measuring cup for accurately measuring your Seachem Reef Fusion 1.

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.
