Marine Magnesium Checker HC, Hanna Instruments

The Marine Magnesium Checker HC from Hanna Instruments is a professional, handheld colourimeter designed for accurate measurement of magnesium levels in saltwater aquariums and marine biology applications. Magnesium is the third most abundant ion in seawater, and its concentration is critical for maintaining a stable aquatic environment. It forms weak ion pairs with carbonate ions, which in turn makes calcium and carbonate available for healthy uptake by corals and invertebrates.

Low magnesium levels can lead to unstable calcium and alkalinity, resulting in the precipitation of insoluble calcium carbonate and impaired growth and health of aquarium inhabitants. This dedicated checker provides a quick, reliable solution for monitoring this essential parameter, helping to prevent these issues and promote a thriving marine ecosystem.
