The Red Sea Magnesium Pro Test Kit is a professional-grade tool designed for the precise measurement of magnesium levels within your saltwater reef aquarium. This advanced test kit is a crucial component of the Red Sea Reef Care Program, enabling aquarists to maintain the optimal water parameters necessary for vibrant coral health. By providing accurate readings, it allows for the correct and safe dosing of magnesium supplements, such as Red Sea's Reef Foundation C, preventing issues associated with unstable magnesium concentrations.

Utilizing an advanced titration method, this kit delivers exceptionally high accuracy with a resolution of just 20 ppm. The testing process involves adding a reagent drop by drop to a water sample until a precise color change occurs, offering a far more reliable result than standard color-comparison test kits. The complete kit includes everything needed for 100 tests, featuring high-quality reagents, a durable glass vial, and a precision syringe for accurate measurements.

This test kit is ideal for dedicated reef hobbyists, particularly those maintaining SPS and LPS coral systems where stable magnesium is vital for skeletal growth and the proper balance of calcium and alkalinity. It is a must-have for aquarists who are dosing supplements, either manually or through an automated system, as it provides the critical feedback needed to adjust dosing and maintain a thriving reef environment.
