Seachem Laboratories Reef Fusion 1 Supplement, 1 gal

Large reefs are hungry for calcium, and keeping a steady supply on hand is part of running them well. Seachem Laboratories Reef Fusion 1 is the calcium component of a two-part reef system, and this is the big 1 gallon size for tanks that go through supplement quickly. Paired with Reef Fusion 2, it is made to help you maintain the calcium and alkalinity a reef aquarium needs.

In a busy reef, calcium and alkalinity are used up together, so a gallon of Reef Fusion 1 lets you keep pace without running short between doses. Seachem describes Reef Fusion 1 and Reef Fusion 2 as the foundation of a system formulated to provide the essentials for the reef aquarium, and notes that when used as directed they maintain the critical levels of calcium and alkalinity while providing biologically appropriate levels of other elements and trace minerals. Set this 1 gallon bottle beside Reef Fusion 2, test on a regular schedule, and dose to your readings so your corals never want for calcium.
