Ionically Balanced Powered Calcium & Alkalinity for all marine fish & reef aquaria


  • The alkalinity-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; economical for particularly large systems.
  • Contains no phosphate, silicate, or organic material.
  • Formulated by a marine scientist.
