Magnesium is a chemical element with the element symbol Mg
Magnesium is extremely important for most reef inhabitants, but especially for corals. Magnesium, together with calcium, is responsible for the alkalinity (KH), the hardness in the water. Magnesium is consumed in seawater aquarium in considerably smaller quantities than eg calcium, but should be measured regularly.
The magnesium content in the water depends on the salt content. The natural concentration of magnesium in seawater is 1310 mg / l (3.5% salt content). The lower the salt concentration, the less magnesium is also contained. In practice, a ratio of 1: 3 between calcium and magnesium should be established in a reef aquarium. That is, at a calcium value of 400 mg / l, the magnesium concentration should be about 1200 mg / l.
The Giesemann Magnesium Test provides an uncomplicated, fast and precise measurement of the magnesium concentration in the aquarium.
By the way: many artificial reef ceramics also give magnesium to the water. This is why it is important to regularly check the concentrations in newly established aquariums.
