The Magnesium Pro Test Kit from Red Sea is a sophisticated titration test which can be used in order to precisely measure the levels of magnesium in your reef aquarium with an incredible accuracy of 20 ppm. The test can be used for accurate dosing of Reef Foundation C supplement, which is a component of the complete Red Sea Reef Care program.

The kit is good for 100 tests. The kit comes with an easy to use, highly accurate titrator, which can be operated by one hand. Also included are a durable, chemical resistant plastic case and analytical grade glass vials.

In order to use the Magnesium Pro Test Kit, you will need to place exactly 2 ml of water into the glass vial using the syringe provided. Afterwards you will need to add 5 drops of Mg Pro Reagent A, making sure to shake the vial for 15 seconds after every drop in order to mix in the reagent. Then you can add 5 drops of Mg Pro Reagent B, gently mixing it in with the rest of the sample.

Screw the glass vial onto the bottom of the titrator. Now wait for approximately 60 seconds. The sample should take on the start color shown in the instruction card and a precipitate will begin to form on the bottom of the vial.

Check so that the dispensing tip is on the 1 ml titration syringe and fill it with 1 ml of titrant. Now insert the syringe into the center of the titrator and add 0.4 ml of titrant while gently swirling the titrator. This is the equivalent to 800 ppm of magnesium. Continue slowly adding more titrant and gently swirling afterwards and note the color changes.

When the color begins resembling the end color shown on the instruction card, start adding only one drop at a time and swirling until you finally achieve the end color. Once the sample reaches the blue end color shown on the instruction card, stop adding any more titrant. The sample should then turn from bleu to violet. If you have added more than 0.8 ml of Mg Pro titrant and this has not happened then you might have missed the end color and will need to redo the test.

Once the end color is reached, note the quantity of titrant used and calculate the magnesium levels in the water using the table provided. Afterwards you can return any unused Magnesium Pro titrant to the bottle.
