Balanced Calcium & Alkalinity System for All Marine Fish & Reef Aquaria Overview The calcium-bearing component of a two-part method for dosing calcium andcarbonates (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 andcarbonates when used in equal amounts with Reef Cōde 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. Sizes 250ml | 500ml | 1L | 2L | 4L | 20L
