Seachem Laboratories Reef Fusion 2 Supplement, 1 gal

For the dedicated reef keeper, alkalinity is one of those numbers you never want to let drift. Seachem Laboratories Reef Fusion 2 is the alkalinity component of a two-part reef system, and this is the large 1 gallon size made for tanks that go through supplement quickly. Paired with Reef Fusion 1, it helps you keep calcium and alkalinity working in balance.

• Supplies alkalinity to your reef aquarium, the carbonate-buffer counterpart to the calcium in Reef Fusion 1.
• Formulated with a mixture of carbonates and bicarbonates at an alkalinity of 4400 meq/L.
• Designed to restore and maintain alkalinity, useful when a heavily stocked reef draws it down fast.
• Provides calcareous species with the essential carbonate Seachem says they need for growth.
• The 1 gallon volume suits large tanks, multiple systems, or anyone tired of frequent reorders.
• Acts as an aquarium water treatment and carbonate buffer within the Reef Fusion system.
• Pairs with Reef Fusion 1 to maintain calcium and alkalinity levels together.
• A liquid supplement that fits straight into a dosing pump or manual routine.
• From Seachem Laboratories, a trusted name among reef hobbyists.
• Always dose as directed and confirm the amount against your own test results.

Bigger and busier reefs pull alkalinity down steadily, so having a gallon on hand means you can keep up without running short between doses. Reef Fusion 1 and Reef Fusion 2 are the foundation of a system formulated to provide the essentials for the reef aquarium, and Seachem notes that using the pair as directed helps maintain the levels your corals rely on. Set this 1 gallon bottle of Reef Fusion 2 beside its calcium partner, test on a regular schedule, and dose to your readings so your reef holds steady through every growth spurt.
