The Magnesium Checker® HC (HI783) is the first marine magnesium test of its kind! This Checker® provides an uncomplicated, accurate, and budget-friendly way to measure magnesium in saltwater/marine environments. Color-coded syringes and straightforward testing steps ensure quick and easy measurements every time! Magnesium is vital in saltwater environments as it allows calcium and carbonate to be bioavailable for corals and invertebrates. Designed as a more accurate alternative to chemical test kits, our Marine Magnesium Checker® HC (HI783) provides quick, accurate results in a few easy steps.
