The Salifert Magnesium Profi Test is a highly accurate and reliable liquid test kit designed specifically for measuring magnesium (Mg) levels in reef and marine aquariums. Magnesium is a vital component for the healthy growth of stony corals and coralline algae.

Maintaining the correct magnesium concentration (ideally between 1300 and 1400 mg/L) is crucial because it prevents the chemical precipitation of calcium and carbonate, allowing you to maintain stable calcium and alkalinity levels in your aquarium ecosystem.
