Brightwell Reef Code A

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.
