FritzPro Magnesium Chloride is a high-quality concentrated magnesium salt that
is designed to replenish magnesium in captive reef systems. Monitoring and
maintaining proper magnesium levels is an important part of stabilizing water
chemistry values, resulting in better coral, coralline algae and invertebrate
growth and health.
Being the third most abundant ion in natural seawater behind sodium and
chloride, magnesium is an important ion for reef aquarists to understand and
monitor. Magnesium is an important part in many biological processes and is an
essential part of calcification. In addition to its many biological functions,
magnesium helps to stabilize the correct combination of calcium, alkalinity and
pH values. Severely low magnesium levels can cause low pH values and the
inability to maintain proper alkalinity and calcium values. Magnesium also
serves to prevent the excessive precipitation of calcium carbonate from
aquarium water.
The recommended level of magnesium in the aquarium is 1250 ppm to 1350 ppm. If
magnesium levels fall below this, calcium has been found to be much more
difficult to get to the proper levels of concentration. Unfortunately,
magnesium often is depleted from reef aquariums as calcification incorporates
it into calcium carbonate skeletons and precipitates. This means magnesium
concentrations that are too low can cause pumps and heaters (and any warm
object) to get coated with precipitating calcium carbonate.
In full strength seawater (salinity = 35 ppt), magnesium is present between
1250 and 1350 ppm.
Magnesium helps to stabilize the correct combination of calcium, alkalinity
and pH values. Severely low values of magnesium (900 mg/L or below) can cause
low pH values and an inability to maintain proper alkalinity and calcium values.

Directions & Dosage
Add one teaspoon (3.5 g) per 10 gallons to raise magnesium by approx. 10 ppm.
Dissolve required amount in RO/DI water and slowly add to a high flow area,
ideally into a sump. Re-test and repeat dose until desired level is reached.
FritzPro Magnesium Chloride can be used in conjunction with FritzPro Mag
Sulfate to more closely match the natural ratio of seawater.
Usage Notes: Always test magnesium levels prior to use. Magnesium
concentration found in natural seawater is between 1250-1350 ppm. Due to the
sensitivity of marine organisms, it is not advisable to raise magnesium by more
than 100 ppm per 24 hours.
Dosage: Add one teaspoon (3.5 g) per 10 gallons to raise magnesium by approx.
10 ppm. Dissolve required amount in RO/DI water and slowly add to a high flow
area, ideally into a sump. Re-test and repeat dose until desired level is
reached.
CAUTION: This product becomes hot when mixed with water; use rubber gloves.
Avoid contact with eyes, skin and clothing. Wash hands after handling.
Storage: Store in a cool, dry place with lid tightly sealed. Keep out of reach
of children.
Note: Due to the variation of granular size, conversion between volume and
weight of powdered products are approximate; as a precaution, dose less than
the calculated amount and measure the effect before adding the total amount.
