Reef-focused: Optimized for seawater magnesium testing
-
Clear end-point: Easy-to-read color change for confident results
-
Fast workflow: Simple steps; result in just a few minutes
-
Repeatable: Calibrated droppers/syringe for consistent dosing

How to Use (Summary)
-
Rinse the test vial with sample water, then fill to the marked line.
-
Add the indicated number of drops of Reagent A; cap and swirl.
-
Add Reagent B by drop (or via syringe, per instructions), swirling between additions until the color shifts to the end-point.
-
Use the provided chart/scale to read Mg (ppm) based on the number of drops (or syringe volume).
-
Rinse all components with fresh water after use.
Target guidance: Many mixed reefs run ~1,280–1,350 ppm Mg. Adjust for your system goals and follow manufacturer dosing directions when correcting.
Best Practices
-
Test at the same time of day for consistency.
