Hanna HI783-25 Magnesium reagent

Hanna HI783-25 Magnesium reagent (seawater) for usage with the Hanna HI783 magnesium checker

Magnesium is the third most abundant ion found in seawater, coming in just after sodium and chloride. Its presence is essential for forming weak ion pairs with carbonate ions, which helps make calcium and carbonate ions available for corals and invertebrates to absorb.

When magnesium levels are low, it can lead to unstable calcium and alkalinity levels. Some signs that magnesium may be lacking include the precipitation of calcium as insoluble calcium carbonate and the impaired growth and health of marine inhabitants.
