Seachem Reef Fusion2 500mL

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.
