Part of the Reef Fusion system—the most concentrated 2-part system on the market—it is dosed in a 1:1 ratio with Seachem Reef Fusion 2 (alkalinity). The 4L format is the most economical choice for large reef aquariums and automated dosing systems with high calcium consumption.\u003c\/p\u003e\n\u003ch2\u003e Main advantages\u003c\/h2\u003e\n\u003cul\u003e\n\n\u003cli\u003e Concentrated ionic calcium at 100,000 mg\/L with integrated essential trace elements\u003c\/li\u003e\n\n\u003cli\u003e 4L size — the most economical in the Reef Fusion range for large systems\u003c\/li\u003e\n\n\u003cli\u003e Includes magnesium, strontium, boron, iron, manganese, and molybdenum in biological ratios\u003c\/li\u003e\n\n\u003cli\u003e Simple 1:1 dosing ratio with Reef Fusion 2\u003c\/li\u003e\n\n\u003cli\u003e Compatible with dosing pumps for automated long-term maintenance\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003ch2\u003e Use in reef aquariums\u003c\/h2\u003e\n\u003cp\u003e Calcium is essential for the growth of SPS and LPS corals, as well as coralline algae.
