    1. Add with the 2 ml syringe 2 ml of water to the test vial.
    2. Add 5 drops of Mg-1 and swirl gently for 30 seconds.
    3. Add one spoon of Mg-2 powder (spoon inside) to the test vial and swirl for 10 seconds.
    4. 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 Ensure that during this that the plastic tip is submersed in hte Mg-3 reagent to avoid that air bubbles are withdrawn instead of liquid. An air layer between the liquid and the piston is normal. The is air which was present between the end of the tip and the piston, this will not influence the result.
    5. Start adding the Mg-3 reagent with the 1 ml syringe to the test vial until the color changes from to gray or blue (whichever color is observed first). Do this drop wise and swirl after each drop for a second or two.
    6. 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 the 0.01 ml. The magnesium concentration can be obtained from the table.

    Been using this ever since day one of my water testing. Highly rated in the hobby. Very reliable and dependable, quick and easy to use. Make sure you get a decent expiration date on your Salifert test kits.
