• Description Accessories (1) Reviews
• PREIS Magnesium Sulphate Heptahydrate is for adding magnesium to sea water. After sodium chloride, magnesium has a higher concentration in natural sea water than any other substance. The magnesium content must often be increased, as shortfalls in the content can arise for various reasons. The normal magnesium content is around 1.350 mg/litre. In order to increase the magnesium content you need PREIS magnesium chloride hexahydrate and PREIS magnesium sulphate heptahydrate for mixing the chloride and sulphate anions in the proportions required for achieving the correct chemical balance.

  Application PREIS Magnesium sulphate heptahydrate
  The mole relationship must be converted to the equivalent weight relationship as salts are sold by weight. You must now calculate how much salt you need for 1 g magnesium.
  7.58 g PREIS magnesium chloride hexahydrate
  + 0.95 g PREIS magnesium sulphate heptahydrate
  = 1 g Magnesium

  Example:
  Aquarium contents 480 l, magnesium content 1270 mg/l
  You are aiming for a magnesium content of 1350 mg/l
  Calculate the shortfall: 1350 mg
  Less 1270 mg
  80 mg x 480 l = 38.4 g magnesium
  38.4 g x 7.58 g magnesium chloride hexahydrate = 291 g
  38.4 g x 0.95 g magnesium sulphate heptahydrate = 36.5 g

  Please weigh the substances using letter or diet scales, dissolve them in water, and add them gradually to the aquarium over a period of several days or for 10 days add each day a 75 ml 5% solution. From the fifth day on measure every two days the magnesium content of the aquarium.
