Product: Salifert Magnesium Profi Test - for about 50 measurements


Magnesium, in nature, is present in seawater in concentrations high enough (1300-1400 mg / l)

Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Photosynthesis also algae and corals, which we keep in our tanks, they could not survive. Magnesium has another important function because it makes it possible to maintain a correct combination of calcium concentration and alkalinity (or carbonate hardness). Calcium forms with carbonates and bicarbonates an insoluble compound called calcium carbonate.

Calcium is an essential element for corals and calcareous algae, but should result from biological processes and be deposited in the right place. Thus the formation of calcium carbonate by chemical processes should be avoided. Even without biological interference calcium carbonate would be formed and this could lower the concentration of calcium and alkalinity without meeting any positive function. Fact this process plundered many trace elements necessary for the health of the aquarium. Magnesium slows down this negative process.

The lower the concentration of magnesium, more velocemnte held this negative phenomenon. Maintain a correct magnesium concentration is very important and is indirectly reflected in the growth of corals (due to chance as possible to maintain stable calcium and alkalinity) Magnesium is diminished by the algae, and from the excessive use of Kalkwasser 'get away from the natural values of calcium, pH and alkalinity. There are also some brands of salt that have a dramatically low magnesium content. Using them means incurring permanent problems with the concentration of calcium and alkalinity values.

The measurement of magnesium assume, in this way is crucial . Magnesium is an element whose role has been undervalued for too long. The magnesium content of many aquariums, when tested, is insufficient. The Salifert magnesium test is very clear and does not suffer the influence of calcium and strontium. Accurate measurement intervals of 30 mg / l with a colorimetric scale very precise.


  1. Take the appropriate syringe, 2 ml of water to be analyzed and put in the clear.
  2. Add 4 drops of liquid water taken from Mg-1, close the container with the blue cap ee shaken gently for 30 seconds
  3. Add a teaspoon (the blue one) of Mg-2 and cap and shake for 10 seconds
  4. Fill the syringe 1 ml. with the liquid Mg-3, refer to the top of the black of the syringe, do not worry about the possible presence of air
  5. Add dropwise the Mg-3 in the container until  the color of the compound contained in it changes from gray to blue, remember to shake after each drop for 1 or 2 seconds
  6. Grab the syringe with the tip up and read the level of Mg-3 remained in correspondence of the black of the syringe.
  7. Compare this value with those reported in the table and you have the concentration of magnesium in the tank.
