Solution of Hydrated Magnesium Salts for Use in Reef and Marine Aquaria.Overview:- Safely increases magnesium concentration in all marine and reef aquaria.
- Utilizes specific magnesium salts to obtain the desired results.
- May be used to attain and maintain a magnesium concentration in excess of 1,500 ppm as desired by aquarist.
- Maintaining an elevated magnesium concentration, relative to the average natural seawater concentration, for a prolonged period of time may be of benefit to reef aquaria in certain situations, and should be attempted by experienced aquarists only.
- 75,000 ppm magnesium
Technical Background:In
some instances, marine and reef aquarists may find it beneficial to
maintain the magnesium concentration in their aquarium within a range of
1,500 - 1,800 ppm for prolonged periods of time. The period of time
will vary between systems and is completely dependent upon the magnesium
concentration that is maintained, as well as the extent to which
maintaining the magnesium at an elevated concentration is associated
with obtaining the desired results.
Additionally,
evidence suggests that the specific magnesium salts utilized are
important to obtaining the desired results. Hydrāt-Mg is a concentrated
magnesium solution that makes use of these specific, hydrated (not
anhydrous) magnesium salts, in proper ionic ratios. Brightwell Aquatics
Magnesion and Magnesion-P are composed of anhydrous magnesium salts,
which offer greater purity than hydrated salts; Magnesion is also more
concentrated than Hydrāt-Mg. Regardless, the conditions that would
dictate that the magnesium concentration in a reef system be maintained
within a range of 1,500 - 1,800 ppm are, in most cases, more rapidly
addressed with Hydrāt-Mg than with magnesium supplements composed of
anhydrous salts. Choosing to maintain an elevated [Mg2+] for an extended
period of time assumes that the aquarist understands the impacts and
potential risks that doing so can have on a marine aquarium.
Instructions and Guidelines:Read
all Instructions carefully. Shake container well before using. If using
to maintain magnesium concentration within a range encompassing
standard seawater concentration, 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 container well before each use.
Each ml of Hydrāt-Mg will increase the concentration of magnesium
("[Mg2+]") in 1 US-gallon (3.785 L) of water by ~19.5 ppm. If the
initial [Mg2+] in the aquarium is below 1,288 ppm, add this product at
the maximum rate of 1 ml per 3 US-gallons daily until the desired
concentration is attained, then dose daily 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 for magnesium maintenance: estimate the volume of
water in the entire aquarium system; divide the daily decrease in [Mg2+]
by 19.5; 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+] than dosing weekly, in which the
[Mg2+] spikes just after dosing and then gradually decreases throughout
the course of the week. Maintaining a stable, elevated [Mg2+] (e.g.
1,800 ppm) for up to 6 weeks may have positive results in some reef
aquaria, however corals and other inhabitants may not respond positively
in all cases. Monitor system carefully and be prepared to move these
organisms to an alternate system with normal [Mg2+] values if necessary.
Guaranteed Analysis: Magnesium (min) 75,000 ppm.
Ingredients: Purified water, hydrated chloride and sulfate salts of magnesium.
