Magnesium per 1000g can

In saltwater aquariums, large amounts of calcium and magnesium are needed to achieve optimal coral and red algae growth. However, the materials normally used in the calcium reactor increase the calcium content more than the magnesium content. This is compensated by adding up to 10% magnesium per material used. This recommended admixture of magnesium per should not be exceeded, as this could lead to an excessive magnesium value in the aquarium. When using Magnesium pro in the aquarium, the magnesium content of the aquarium water should be checked regularly.
