      Description

      Magnesium¹²+ is a concentrated magnesium supplement formulated for reef aquariums. It is intended for occasional correction when magnesium levels fall below the natural seawater range (1,280–1,350 ppm). Unlike daily maintenance formulas, Magnesium 12+ delivers magnesium alone, without additional trace ions, making it ideal for safely raising levels without disturbing balance. Each mL increases magnesium by 10 ppm per 1 US gallon (3.8 L).

      Instructions 

      Test magnesium with a reliable kit before dosing.

      Calculate dose: 1 mL per 1 US gallon = +10 ppm magnesium 1 mL per 10 US gallons = +1 ppm magnesium

      Dose safely: Do not increase magnesium by more than 50–100 ppm per day. Add dose gradually into a high-flow sump or display area. Re-test magnesium after 12–24 hours before repeating.

      Example: In a 100-gallon system, 500 mL (≈1 bottle) raises magnesium by ~+50 ppm.
