• The calcium-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 CODE B.

• 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.

• Liquid
• 500-ml
