Magnesium is a crucial element in saltwater environments, as it allows calcium and carbonate to be bioavailable for corals and other invertebrates. Therefore, consistent and accurate testing of magnesium levels in your marine aquarium is vital to ensure a healthy and thriving system.
The HI783 Magnesium Checker HC by Hanna Instruments provides a simple, accurate, and affordable way to measure magnesium in saltwater/marine environments. Its color-coded syringes and straightforward testing strips ensure quick and hassle-free measurements, every time. With a digital readout, there is no more struggling to determine colors visually.
