Features
- 500ml / 17 fl. oz
- 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.
Description
Magnesion
Highly-concentrated ionic magnesium solution.
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.
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.
