The Red Sea Test Refill Magnesium Pro is a high-accuracy titration test kit refill designed for reef aquariums. It allows aquarists to easily and reliably monitor magnesium levels, which are essential for maintaining proper calcium and alkalinity balance. Stable magnesium ensures healthy coral growth, strong skeletal development, and an overall stable marine environment. This refill pack provides everything needed to continue testing without purchasing a full new kit, making it a cost-effective and sustainable option.
High-Precision Testing: Measures magnesium levels with an accuracy of ±20 ppm, ideal for reef aquariums.
Supports Coral Health: Helps maintain proper ionic balance necessary for coral skeleton formation and vibrant coloration.
Economical Refill Pack: Includes enough reagents for up to 100 tests, extending the life of your existing Magnesium Pro kit.
Easy to Use: Designed for use with the Red Sea Magnesium Pro test kit hardware, ensuring consistent and accurate results.
Part of Reef Care Program: Works seamlessly with Red Sea’s Foundation tests to maintain balanced calcium, magnesium, and alkalinity.
Use in combination with your existing Red Sea Magnesium Pro kit.
Follow the step-by-step titration method provided in the original kit’s manual.
Recommended testing frequency: once or twice a week, or more frequently in heavily stocked reef tanks.
Refill reagents for 100 magnesium tests (no glassware or syringes included).
For Reef Aquariums: Especially important for SPS and LPS coral tanks that consume magnesium rapidly.
Balanced Reef Chemistry: Use alongside Red Sea Calcium Pro and Alkalinity Pro test kits for complete monitoring.
Target Range: Maintain magnesium levels between 1,280 – 1,350 ppm for optimal reef health.
