The Salifert Magnesium Profi Test Kit is a simple and accurate way to measure the magnesium levels in your marine aquarium.
Magnesium is an essential element for coral and other marine life, and maintaining the correct levels is important for their health and growth.

The Salifert Magnesium Profi Test Kit uses a colorimetric method to measure magnesium levels.
This means that you will compare the color of your test sample to a color chart to determine the magnesium concentration.

The kit includes everything you need to perform the test, including:

  • Instruction manual
  • Plastic vial
  • Measurement spoon
  • Syringes (2ml and 1ml)
  • Reagents (Mg-1, Mg-2, and Mg-3)

  • The test is accurate to within +/- 0.1 mg/L
  • It measures in sufficient accurate steps of 30 mg/L with a sharp color change.
  • The test results are available in minutes
  • The kit includes enough reagents for 50 tests

Magnesium is present in natural seawater in a fairly high concentration (1300 - 1400 mg/L). Magnesium is an essential part of chlorophyll, which is necessary for photosynthesis. Without photosynthesis plants, including algae and the corals, which we usually have in our aquariums, would not be able to live.

Magnesium has another important function since in fact makes maintaining the correct combination of calcium concentration and alkalinity or carbonate hardness possible.

The explanation is as follows. Calcium forms with carbonates and bicarbonates an insoluble compound called calcium carbonate.
Yes this is indeed an important building stone for corals and calcareous algae but then it should be formed by biological processes and be deposited at the right place.
Therefore formation of calcium carbonate by chemical processes should be avoided.

Even without biological interference calcium carbonate would be formed and would deplete calcium and alkalinity or carbonate hardness without fulfilling any function.
In fact it will scavenge many important trace elements as well lowering the trace element concentration.

Magnesium slows down this negative process.
The lower the magnesium concentration the faster this negative process will take place and also at a much lower calcium and alkalinity/carbonate hardness value.

Maintaining a correct magnesium concentration is therefore very important and is indirectly responsible for fast coral and calcareous algae growth by virtue of making the maintenance of correct calcium and alkalinity figures possible.

Magnesium is depleted by algae and is also depleted by the use of excessive kalkwasser and by going far beyond natural calcium and alkalinity and pH values.

There are also certain brands of salt, which have or had a dramatically low magnesium content.
Use of such a salt will result in permanent problems with calcium and carbonate hardness values.

The Salifert magnesium test is very straightforward and does not suffer from calcium and strontium interferences when within certain bounds.
