Maintain perfect alkalinity balance in your reef tank with Seachem Reef Fusion 2, a concentrated blend of carbonates and bicarbonates designed to:
-
Raise and stabilize alkalinity at 4400 meq/L—critical for coral skeleton growth
-
Support healthy coral development, especially when paired with Reef Fusion 1
-
Provide essential carbonate ions without affecting pH
-
Work efficiently in both low and high-demand reef systems
How to Use: Shake well before dosing. Add 1 mL per 25 L of aquarium water every 1–2 days into a high-flow area. Always dose separately from Reef Fusion 1 and test regularly to fine-tune your routine.
Reef Fusion 1™ and Reef Fusion 2™ are the foundation of a system formulated to provide the essentials for the reef aquarium. Reef Fusion 1™ provides calcium, while Reef Fusion 2™ provides alkalinity. When used together, the Reef Fusion™ system will maintain calcium and alkalinity levels.
