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), ie the hardness in the water. Magnesium is consumed in seawater aquarium in significantly lower amounts than eg calcium, but should still be measured regularly.
The magnesium content in the water depends on the salt content. The natural concentration of magnesium in seawater is 1,310 mg / l (3.5% salinity). The lower the salt concentration, the less magnesium is included. In practice, a ratio of 1: 3 between calcium and magnesium should be set in a reef aquarium. This means that with a calcium value of 400 mg / l, the magnesium concentration should be around 1200 mg / l.
The Giesemann Magnesium Test offers an uncomplicated, fast and yet precise measurement of the magnesium concentration in the marine aquarium.
By the way: many artificial reef ceramics also release magnesium to the water. That is why it is important to regularly check the concentrations even in newly established aquariums.
