Balanced Calcium & Alkalinity System for All Marine Fish & Reef Aquaria


  • The carbonate-bearing component of a two-part method for dosing calcium and
    carbonates (the substances largely responsible for increasing alkalinity
    (”buffering capacity”)) in the same ratio as that found in natural seawater.
  • Unlike single component KH products such as sodium carbonate, Reef Code B

     is a multi-component automatic buffer that regulates pH and its use makes for a
     much more stable aquarium.  Eliminates pH and KH instability caused by poor salt mixes
     and ineffective buffering products.  Also adds multiple major, minor and trace minerals.

  • Ionically-balanced with respect to natural seawater concentrations of calcium and
    carbonates when used in equal amounts with Reef Cōde A.
  • Benefits reef-building organisms such as corals, clams, calcareous algae, etc.
  • Simplifies calcium and alkalinity maintenance.
  • Stronger than most competing products.
  • Contains no phosphate, silicate, or organic material.
  • Formulated by a marine scientist.
