Description
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.
Why the 1 gallon size earns its place on your stand:
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.
