NT Labs Marine Lab Magnesium Test Kit, Marine Aquarium Water Testing Kit, Accurate Results, Contains up to 35 Tests.

【 MONITORS MAGNESIUM LEVELS IN MARINE AQUARIUMS】: Magnesium is the second-most abundant cation found in natural seawater. Magnesium is essential for the efficient assimilation of calcium by marine invertebrates. Without the correct levels of magnesium, corals and invertebrates cannot properly or efficiently utilise calcium for the formation of their shells and growth of skeletons. Sufficient magnesium also prevents precipitation of calcium and carbonate ions, ensuring bioavailable calcium and a pH stabilising effect. As magnesium tends to deplete with the age of the water, monitoring the magnesium frequently is the only reliable method to determine the concentration present in the water. 【 EASY TO USE】: Use the 1 ml pipette to measure 1 ml of water to be tested into the titration vessel. Add 10 drops of Mg-1 reagent. Add 5 drops of Mg-2 reagent to turn the sample pink in colour. Attach the titration tip to the 1 ml syringe provided. Draw up 1 ml of Mg-3 so that the bottom of the plunger is at the 1.0 ml mark. Slowly dispense from the syringe into the titration vessel while swirling. Keep dispensing from the syringe. Slow down when the colour of the solution changes from pink to purple. Stop dispensing from the syringe when the solution is blue. Read the syringe then look up this value on the chart to determine the calcium concentration. 【 HOW TO FIX MAGNESIUM ISSUES 】: The average magnesium level in natural seawater is 1300-1400 mg/l. Equally importantly, the correct ratio between magnesium and calcium should be achieved. The concentration of magnesium should be 3 times that of calcium (e.g. a magnesium to calcium of 3:1). If the magnesium concentration in your aquarium is wrong, partial water changes using a good quality reef salt is recommend to help re-establish the correct magnesium concentration. It is also important to check the calcium and KH as the three are correlated. If the magnesium is incorrect, calcium and KH are also likely to be wrong. 【 ACCURATE LIQUID DROP TESTS 】: All NT Labs water testing kits are liquid drop tests from a dropper bottle to ensure the drops are the same size. This method of testing is significantly more precise compared to using dip strips. The use of liquid reagents guarantees accurate and dependable results for each parameter, simplifying the process of monitoring and maintaining ideal water conditions in your aquarium. 【 SUITABLE FOR ALL AQUARISTS 】: The ease of use of NT Labs Test Kits means they are perfect for use by beginners and seasoned aquarists alike.
