Concentrated Magnesium Supplement for All Marine Fish & Reef Aquaria.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.
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.
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.
