Test Magnesium Mg profi test Salifert

Profi Test Magnesium allows you to monitor the magnesium present in your marine aquarium. This product, in two solutions, allows you to perform 50 tests. Our opinion: Salifert tests are reliable and very affordable.

Magnesium WARNING: Keep out of reach of children! Do not swallow! Calcium will not interfere if their concentration is between 300 and 500 ppm, which is the most common case.

INSTRUCTIONS:

There will be air present just below the syringe pistons filled with 2 ml and 1 ml. This is the air that was present between the end of the plastic tip and the piston. DO NOT try to eliminate this air, for example by repeatedly purging the syringe.

1] Pour 2 ml of the water to be tested into the test tube using the syringe.

2] Add 5 drops of reagent Mg-1 and stir gently for 5 seconds.

3] Place the plastic cone firmly on the 1 ml syringe, and fill it with reagent Mg-2 until the lower part of the black piston is at the 1.00 ml graduation. During this operation, ensure that the cone remains submerged in reagent Mg-2 to avoid drawing in air bubbles instead of liquid. An air layer between the piston and the liquid is normal. This is the air that was present between the end of the cone and the piston. It will not influence the result.

4] Begin adding reagent Mg-2 to the test tube using the 1 ml syringe until the color turns gray or blue (regardless of the initial color). Stir for a second or two after each drop added.

5] Holding the syringe with the cone facing up, read the position of the upper part of the piston. Each graduation corresponds to 0.01 ml. The magnesium concentration can be obtained using the table.

Natural seawater contains a magnesium concentration of around 1280 ppm. The concentration varies with salinity.
