Magnesium is essential for the efficient assimilation of calcium by marine invertebrates.\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nWhy test for magnesium?\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nWithout 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.\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nWhat is the correct level of magnesium?\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nThe 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).\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nWhat to do if the magnesium level is wrong?\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\nIf 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.\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Features:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eEasy to use\u003c\/li\u003e\n\u003cli\u003eFast \u0026amp; accurate results\u003c\/li\u003e\n\u003cli\u003eTests for Magnesium\u003c\/li\u003e\n\u003cli\u003eContains 35 Tests\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\n\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to use:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eUse the 1 ml pipette provided to measure 1 ml of water to be tested into the titration vessel\u003c\/li\u003e\n\u003cli\u003eAdd 10 drops of Mg-1 reagent.
