Seachem’s Reef Fusion system acts as a two‑part foundation that delivers what corals and calcareous inhabitants need to grow in a balanced environment. When used together, Reef Fusion 1 and Reef Fusion 2 help keep calcium and alkalinity within target ranges, while ensuring other trace minerals are present at biologically appropriate levels. This approach supports steady, natural-looking reef development without guesswork.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s in the Reef Fusion system\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReef Fusion 1 provides calcium in ionic form ready for uptake by calcifying organisms.\u003c\/li\u003e\n  \u003cli\u003eReef Fusion 2 supplies carbonate and bicarbonate to restore and maintain alkalinity.\u003c\/li\u003e\n  \u003cli\u003eTogether, they form the most concentrated two‑part system in Seachem’s lineup, designed for a simple 1:1 dosing workflow.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey benefits in the aquarium\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCalcium supplied at about 100,000 mg\/L of ionic calcium to support growth and skeletal formation.\u003c\/li\u003e\n  \u003cli\u003eAlkalinity restoration and ongoing maintenance help stabilize carbonate availability for corals.\u003c\/li\u003e\n  \u003cli\u003eDesigned to provide calcareous species with essential carbonate for skeletal development.\u003c\/li\u003e\n  \u003cli\u003eSimple dosing with a clear 1:1 ratio makes routine maintenance straightforward and predictable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow to use Reef Fusion 1 and 2\u003c\/h3\u003e\n\u003cp\u003eFollow the label directions for the 1:1 dosing approach.
