Salifert Mg Magnesium Profi Test 50 tests
Salifert Mg- Premium liquid magnesium test kit for marine aquariums.
Precise magnesium measurement in increments of 30 ppm.
Maintain proper magnesium level for healthy reef aquariums.
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.
Range: 30 to 1500 ppm
Why Test Magnesium?
Magnesium is essential for all photosynthetic organisms including corals and invertebrates with symbiotic algae. Magnesium also helps maintain the correct combination of calcium concentration and alkalinity in seawater. Therefore, proper magnesium concentration is very important for a stable marine environment with healthy inhabitants.
Magnesium Profi Test
The magnesium test can be used for testing Marine water only. Calcium and strontium will not interfere when their total concentration is between 300 and 500 ppm. This is mostly the case.
WARNING Keep out of reach of children. Not for consumption.
Add with the 2 ml syringe 2 ml of water to the test vial.
Add 5 drops of Mg-1 and swirl gently for 30 seconds.
Add one spoon of Mg-2 powder (spoon inside) to the test vial and swirl for 10 seconds.
Place the plastic tip firmly on the 1 ml syringe and draw into this Mg-3 reagent until the lower end of the black syringe part is at the 1.00 ml mark. Ensure that during this process that the plastic tip is submersed in the Mg-3 reagent to avoid drawing in air bubbles instead of liquid. An air layer between the liquid and the piston is normal. This is air, which was present between the end of the tip and the piston that will not influence the result.
Start adding the Mg-3 reagent with the 1 ml syringe to the test vial until the color changes to gray or blue (whichever color is observed first). Do this drop-wise and swirl after each drop for a second or two.
Hold the syringe with the tip facing upward and read the position of the upper end of the black syringe part. Each division corresponds to 0.01 ml. The magnesium concentration can be obtained from the table.
Natural seawater has a magnesium concentration of approx. 1300-1500 ppm. The concentration varies with salinity. Too low magnesium concentration makes maintaining correct calcium and alkalinity concentration difficult.
