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.

Reef Code A
Technical Background
This method of calcium and carbonate supplementation is
advantageous to hobbyists interested in a simple and effective
means of providing the very elements and molecules required for
growth of reef-building organisms such as corals, clams, and
their allies. Corals and other reef-building organisms require
adequate and stable available calcium and alkalinity if they are
to thrive, regardless of how perfect the remainder of their
environment is. Under most conditions, the mineral that is
secreted as skeletal material is known as Aragonite, composed
mostly of carbonate and calcium by weight. Reef-building
organisms must extract these substances from the surrounding
water in order to secrete new skeletal material for growth. By
maintaining the same ratio of calcium ions and carbonates in an
aquarium as that found in natural seawater, these organisms have
the necessary building blocks available in the proper
proportions, even if the hobbyist chooses to maintain higher
concentrations of these substances.
For maximum effectiveness of the Reef Cōde method, the magnesium
concentration in reef aquaria should be adjusted to, and
maintained between, 1,290 - 1,320 ppm before using these
products (alone or together) or any other calcium and alkalinity
products. Doing so helps prevent unwanted precipitation between
calcium and carbonate ions. Additional information on this
subject is available on our website and on the label for
Brightwell Aquatics Magnesion.
The rate at which calcium and carbonates are extracted from the
water is determined by the stocking density of reef-building
livestock, type of lighting, and other conditions; therefore,
each aquarium will have different requirements for the rate of
supplementation. Once the rate of calcium uptake in the aquarium
has been determined, the proper dosing rate of this product can
be easily calculated.
Instructions and Guidelines
Basic: 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 Cōde B, the calcium and carbonates being added
are in the same ratio found in natural seawater. Do not mix
products in the same container; this will cause the active
components to precipitate and become ineffective. Allow 60
seconds to pass between dosing Reef Cōde A and B.
Advanced: Determine the calcium concentration in the
aquarium using an accurate test kit before supplementing. Shake
this product well before each use. Each ml of Brightwell
Aquatics Reef Cōde A will increase the concentration of calcium
(“[Ca2+]”) in 1 US-gallon (3.785 L) of water by approximately 16
ppm. If the initial [Ca2+] in the aquarium is below 412 ppm, add
this product at the maximum rate of 5 ml per 10 US-gallons daily
until the desired calcium concentration is attained, then dose
daily or weekly as needed (see below). Note that each aquarium
has different requirements for calcium and carbonates (which
largely constitute Alkalinity or Buffering Capacity, hence
pH-stability); therefore, it is not uncommon for unequal amounts
of Reef Cōde A and B to be required for obtaining and
maintaining the desired calcium concentration and alkalinity. To
determine the daily dosing rate for calcium maintenance:
estimate the volume of water in the entire aquarium system;
divide the daily decrease in [Ca2+] by 16; multiply this number
by the volume of water in the system to get the daily dosage
required (ml) to maintain a stable [Ca2+].
Caution: May cause eye or skin irritation.
Flush with water for 15 minutes if in eyes, seek medical
attention if irritation persists. Keep out of reach of children.
Not for human consumption.
