Reef Code B

• 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.
• Ionically-balanced with respect to natural seawater concentrations of calcium and carbonates when used in equal amounts with Reef Cõde 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.
