Seachem Reef Fusion 2 is specially formulated to supply your tank with the essential carbonates, bicarbonates and alkalinity to help your corals grow. This is the second of the Reef Fusion system that helps maintain proper alkalinity for a healthy live reef environment.

  • Maintains proper alkalinity levels for healthy coral growth
  • 2-part Reef Fusion system maintains calcium and alkalinity levels
  • Supplies tank with needed carbonates, bicarbonates and alkalinity

Reef Fusion 2 contains a mixture of carbonates and bicarbonates at an alkalinity of 4400 meq/L. It is designed to restore and maintain alkalinity in the reef aquarium and provide calcareous species with the essential carbonate needed for growth.

Directions: Dose aquarium every 1-2 days. Shake well before using. Add 1 ml of Reef Fusion 1 per 25 L (6.5 US gallons) of water. (For reference purposes, the cap holds 5 ml.) Add this to a high current area of the tank. Wait a few minutes, then add Reef Fusion 2 in the same manner, 1 ml per 25 L (6.5 US gallons), after shaking well. It is preferred that the two products be added to separate locations in the tank. This dose contributes 4 mg/L of calcium, and 0.176 meq/L of alkalinity. Never mix Reef Fusion 1 with Reef Fusion 2 directly.

Note: Do not exceed a dose of 4 ml in 25 L (6.5 US gallons) per day of each product.

Maintain calcium level between 410-430 mg/L. Maintain alkalinity between 4-6 meq/L. Size or frequency of dose may be increased if dosing regimen is insufficient to maintain calcium and alkalinity in these ranges.
