Description:

Seachem Reef Fusion 2 adds in 1000,000 mg/L of ionic calcium as well magnesium, strontium, boron, iron, manganese and molybdenum.

Reef Fusion 2 

  • Provides 1000,000 mg/L of ionic calcium
  • Restores and maintains alkalinty
  • Most concentrated two part system; simple 1:1 ratio

  • 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.

    Reef Fusion 1 provides not only 100,000 mg/L of ionic calcium, but also includes biologically appropriate levels of magnesium, strontium, boron, iron, manganese, and molybdenum.

    Reef Complete is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete is blended to a higher pH in order to force the ammonia to gas off into the atmosphere. In addition, Reef Complete is more concentrated than any other liquid product on the market. Reef Complete contains 160,000 ppm calcium. Our nearest competitor’s product is only 110,000 ppm calcium.

    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.

    When used as directed, Reef Fusion 1 and Reef Fusion 2 will maintain the critical levels of calcium and alkalinity necessary for healthy coral growth, while providing biologically appropriate levels of other elements and trace minerals.

    Directions
  • Dose aquarium every 1-2 days.
  • Shake well before using.
  • Add 1 mL of Reef Fusion 1 per 25 litres of water.
  • 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 litres, 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.

  • DO NOT EXCEED A DOSE OF 4 mL IN 25 litres 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.
