The Salifert Magnesium Profi Test makes testing magnesium levels easy and accurate. Reef aquarium enthusiasts have relied on the precision quality of Salifert test kits for years. Monitor and maintain magnesium levels without fear of skewed test results due to strontium or calcium interference. Salifert Magnesium Test kit is an essential part of any magnesium- or any reef-supplementation regimen.

For use in marine aquariums only. Sufficient for up to 50 tests.



  • Use the syringe and add 3 ml of water into the test vial.
  • Add 6 drops of Mg-1 and swirl gently for 30 seconds.
  • Add 1 spoon of Mg-2 powder (spoon inside) to test vial and swirl for 10 seconds.
  • Put the plastic tip firmly on the syringe. Make sure the plastic tip of the syringe is constantly submersed in the Mg-3 reagent. Then draw the Mg-3 reagent into the syringe until the lower end of the black piston is exactly at the 1.00 ml mark. There will be some air present just below the piston. This is the air that was present between the end of the plastic tip and the piston. This will not influence the test result.
  • Add the Mg-3 reagent with the syringe, one drop at a time, into the test vial until the colour changes to gray or blue (whichever colour is observed first). Be sure to swirl the test vial for 1-2 seconds after each drop.
  • Hold the syringe with the tip facing upward. Read the position of the black syringe. Each division corresponds to 0.01 ml.
