MAGNESIUM TEST
Kit consisting of:
What is Magnesium
Magnesium is one of the elements present in greater quantities in sea water; after Sodium and Chlorine, Magnesium is in fact the most abundant element. Its concentration is approximately three times that of Calcium and is around 1200 mg/L. Like Calcium,
Magnesium also enters into the calcification processes of the skeletons of corals and coralline algae.
Why measure it
In addition to intervening in numerous physiological processes, a correct presence of Magnesium in the water helps to contain the precipitation of Calcium carbonate. It is therefore important to maintain the correct weight ratio (mg/L) between Magnesium and Calcium, which should be around 3 (in fact: 1200:4=3).
How to do the test
1. Rinse the test tube repeatedly with the water to be analyzed.
2. Fill the test tube with 2 mL of water to be analyzed.
3. Add 5 drops of Mg 1 reagent and shake the test tube for about 20 seconds.
4. Add 5 drops of Mg 2 reagent and shake the test tube, the solution will turn red-violet.
5. Fit the plastic tip on the tip of the syringe, aspirate 1 mL of Mg 3 reagent and slowly insert it into the test tube until the water sample changes color from red-violet to blue. The number of tenths of a mL needed to change the color of the liquid in the test tube will indicate the Magnesium content based on the notes in the table on the back of this leaflet. It is also possible to calculate the Magnesium content by multiplying the number of mL needed to change the color of the liquid in the test tube by 1,500. Example: 0.90 mL of Mg 3 needed to change the color from red-violet to blue X 1,500 = 1,350 mg/L of Magnesium.
