Magnesium keeps calcium in solution longer. Since calcium and magnesium are consumed in every marine aquarium, magnesium must be added to restore the correct concentration ratio between the earth alkali metals.
Power Magnesium and Magnesium liquid also prevent magnesium deficiency. One dosage spoon of Power Magnesium increases the magnesium content by 10 mg/100 l.
Magnesium liquid is suitable for dosing pumps. 10 ml increases the magnesium content by 5 mg/100 l.
