The Checker® provides a simple, accurate, and cost-effective way to measure magnesium in marine/saltwater environments. Color-coded syringes and a few easy steps ensure quick and hassle-free testing every time. Magnesium is vital in saltwater systems, as it allows calcium and carbonate to remain bioavailable for corals and invertebrates.

Designed as a more precise alternative to test kits, our HI783 Marine Magnesium Checker® delivers quick and accurate results in just a few easy steps.

Additional features:

• Fewer steps than other chemical tests

• Color-coded syringes make magnesium testing simple and effortless

• Dedicated to a single parameter

• Small size, big convenience

• Ideal for: saltwater aquariums, marine, and aquaculture applications
