- 75 titration tests each for borate, carbonate & magnesium.
- Directly measures magnesium.
- Measures carbonate and borate alkalinity.
- Interference free.
- Easy test validation with included reference.
Natural seawater concentration for magnesium is approximately 1,300
mg/L. The magnesium concentration in kalkwasser treated aquaria may be
as low as 600 – 700 mg/L. In general, it is prudent to maintain
magnesium concentrations in reef aquaria between 1,200–1,400 mg/L.
Natural
seawater has a total alkalinity of about 2.5 meq/L, of which about 0.1 –
0.2 meq/L is from borate. In an aquarium, it is advantageous for both
pH control and improved calcium stability to have a higher borate
content. This, however, should not be at the expense of carbonate. It is
useful, then, to maintain a total alkalinity of about 4 – 5 meq/L with a
borate component of about 1.5 – 2.0 meq/L.
Features:Reef
Status Magnesium is capable of at least 75 tests for magnesium, total
alkalinity, borate alkalinity, and carbonate alkalinity. It is designed
specifically for seawater.
Accuracy:Range:Magnesium: 125 mg/L and over 1250 mg/L
Alkalinity: 1 meq/L and over 10 meq/L
Precision:Detectable changes in the following increments:
Magnesium: 12.5 mg/L
Alkalinity: 0.1 meq/L
Reference Sample:It
isn't necessary to run a reference test to use this kit; however, its
proper performance can be validated by running a test in the normal
manner except that the reference sample is used in place of aquarium
sample. You might choose to run a reference test if you have cause to
believe the test is giving incorrect results.
Magnesium:The
test is based on titration of magnesium with EDTA in the presence of a
magnesium specific indicator dye after the coprecipitation of calcium
and strontium. During the testing procedure, the sample transitions
between pink and blue. Once the sample turns blue, the test is complete.
Magnesium concentration corresponds to markings on the titration
syringe.
Alkalinity:The
test is based on titration of carbonate and/or borate with acid in the
presence of a pH indicator dye (endpoint = pH 4 for total alkalinity and
endpoint = pH 6 for borate alkalinity). During the testing procedure,
the sample transitions between blue and yellow. Once the sample turns
yellow, the test is complete. Alkalinity levels correspond to markings
on the titration syringe.
