Overview
• Highly-concentrated ionic magnesium solution.
• Provides magnesium, which
helps regulate the balance between calcium and carbonates in aquarium water,
and is a component of aragonite, the mineral secreted by reef-building
organisms such as corals, clams, and their allies to form skeletal material.
• Stronger than most
competing products.
• Contains no unwanted
organic material such as EDTA, gluconate, or polygluconate.
• Formulated by a marine
scientist.

Magnesion
Technical Background
Magnesium plays a vital role in reef aquaria: it helps maintain
calcium and carbonate (composing the majority of measurable
alkalinity) concentrations by limiting unwanted inorganic
precipitation with each other. In the absence of adequate
magnesium ions, calcium and carbonate ions bond rapidly,
depleting their concentrations in the system and creating the
false impression that heavier supplementation is required to
re-establish the desired concentrations. No matter how much
calcium is added, its natural seawater concentration of 412 ppm
will never be sustained until the magnesium concentration begins
to approach 1,290 ppm. Once the balance between calcium and
magnesium has been established, subsequent calcium
supplementation yields immediate positive results. Keeping
magnesium within a range of 1,290-1,320 ppm will maintain the
desired balance, and provides enough of the element to
reef-building organisms for the formation of aragonite (~0.10%
Mg by weight).
The rate at which magnesium is 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 magnesium
supplementation. Once the rate of magnesium uptake in the
aquarium has been determined, the proper dosing rate of this
product can be easily calculated. It is recommended that a
quality salt mix with the proper (not augmented) alkalinity and
concentrations of major, minor, and trace elements be used to
establish natural seawater parameters in the reef aquarium,
providing a stable ionic foundation on which to build.
All Brightwell Aquatics liquid water care supplements are made
with purified water and high purity materials. We develop
formulae for aquaria based on empirical data, using observation
and measurement rather than theory.Instructions and Guidelines
Basic: Shake product well before using. Add 5 ml (1
capful) of product per 20 US-gallons of aquarium water every
other day or as needed to maintain the magnesium concentration
within a range of 1,290 - 1,320 ppm. When used in this fashion,
250 ml treats up to 1,000 US-gallons (3,785 L).
Advanced: Determine the magnesium concentration in the
aquarium using an accurate test kit before supplementing. Shake
this product well before using. Each ml of Magnesion will
increase the concentration of magnesium (“[Mg2+]”) in 1
US-gallon (3.785 L) of water by 26 ppm. If the initial [Mg2+] in
the aquarium is below 1,288 ppm, add this product at the maximum
rate of 10 ml per 20 US-gallons daily until the desired
concentration is attained, then dose daily or weekly as needed
(see below). Always try to maintain the [Mg2+] within a range of
+/-10 ppm. To determine the dosing rate of this product once the
desired [Mg2+] has been acquired, measure the daily rate of
magnesium uptake (i.e. the decrease in magnesium) in your
aquarium by measuring the aquarium's [Mg2+] at the same time
each day over a one- to two-week period. To determine the daily
dosing rate (preferable to weekly dosing) for magnesium
maintenance: estimate the volume of water in the entire aquarium
system; divide the daily decrease in [Mg2+] by 26; multiply this
number by the volume of water in the system to get the daily
dosage required (ml) to maintain a stable [Mg2+]. Daily dosing
maintains a more stable [Mg2+] (and more natural environment)
than dosing weekly, in which the [Mg2+] spikes just after dosing
and then gradually decreases throughout the course of the week.
Caution: Keep out of reach of children.
Not for human consumption.
