MAGNESIUM (Mg) TEST KIT INSTRUCTIONS

Why Do MAGNESIUM Tests?
Magnesium also contributes to the overall hardness along with calcium. Similar to potassium, magnesium is a macroelement that corals need to grow healthily and vigorously. Beautiful calciferous red algae cannot thrive and coral cannot grow when calcium and magnesium levels are too low.
Directions
Remove safety cap:
1. Fill a clean test vials with 4 ml of water to be tested (to the line on the vials).
2. Add 10 drop of the reagent No. 1 then add 2-3 spoon solid reagent Shake well The sample solution turns purple-red. 3. Use a 1-ml syringe to draw 1ml of No. 2 reagent and add it dropwise into the water sample while shake 2-3 seconds after adding each drop. When the color of sample solution changes from purple-red to sky blue, record the volume added. The concentration of Magnesium ion can be obtained from the table.
PRECAUTIONS:

1.Shake the reagent well before use. This test reagent is suitable for fresh water and sea water.

2. Rinse the syringe and test cup with purified water immediately after use.

Recommended Mg Levels
Aquarium with marine water: 1200–1600 mg/l
The recently employed magnesium salts and trace elements in the sea salt mixture created a departure of roughly 20–30% from the original marine water.
