Brightwell Aquatics Reef Code A - Balanced Calcium & Alkalinity System

Overview 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 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.   Instructions and GuidelinesBasic: Shake product well before using. Add 5 ml (1 capful) of product per 25 US-gallons of aquarium water every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. When used in this fashion, 250 ml treats up to 1,250 US-gallons (4,732 L). When used in equal amounts with Reef Code B, the calcium and ca
