Description
Reef Fusion 2 is the alkalinity half of Seachem’s two-part system, supplying carbonates along with the trace elements that belong with them. Dosed in equal parts with Reef Fusion 1, it holds calcium and alkalinity in balance as corals draw both down.
Alkalinity punishes swings harder than any other major parameter – it moves faster than calcium and corals feel it first, usually as tip burn or receded tissue after a sharp correction. Dose consistently, daily rather than in big weekly slugs, and verify with a decent test kit.
This size is the economical pick if you dose daily or run a larger system.

- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
