Adjust the magnesium level as needed to prevent a deficiency. The reference range given here for natural seawater is 1250\u20131380 mg\/l, with seasonal and geographical variation.<\/p>\n<p>Use hw\u00ae Magnesium Chloride Hexahydrate together with a precisely measured amount of hw\u00ae Magnesium Sulfate Heptahydrate to avoid an unfavourable change in the chloride-to-sulfate ratio.<\/p>\n<h4>General procedure<\/h4>\n<p>The quantities account for molar masses, water of crystallisation and the chloride-to-sulfate ratio. Use the following combination to supply 1.00 g of magnesium:<\/p>\n<ul>\n<li>0.95 g hw\u00ae Magnesium Sulfate Heptahydrate (MgSO\u2084 \u00b7 7H\u2082O)<\/li>\n<li>7.58 g hw\u00ae Magnesium Chloride Hexahydrate (MgCl\u2082 \u00b7 6H\u2082O)<\/li>\n<\/ul>\n<h4>Example<\/h4>\n<p>A marine aquarium containing 500 l of water has a magnesium level of 1200 mg\/l. Raising it to 1300 mg\/l requires an additional 100 mg\/l \u00d7 500 l = 50 g of magnesium.<\/p>\n<ul>\n<li>50 g \u00d7 0.95 = 47.50 g hw\u00ae Magnesium Sulfate Heptahydrate<\/li>\n<li>50 g \u00d7 7.58 = 379.00 g hw\u00ae Magnesium Chloride Hexahydrate<\/li>\n<\/ul>\n<p>Dissolve both salts together in 600 ml of reverse osmosis water, then make up to 1000 ml. Add 100 ml per day over the next 10 days. Check the aquarium magnesium level on day 5 and adjust if
