{"product_id":"magnesium","title":"Magnesium¹²+","description":"\u003cp\u003e\u003cstrong\u003eMagnesium¹²+\u003c\/strong\u003e 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).\u003c\/p\u003e\n\u003ch2\u003eInstructions \u003c\/h2\u003e\n\u003cp\u003eTest magnesium with a reliable kit before dosing.\u003c\/p\u003e\n\u003cp\u003eCalculate dose: 1 mL per 1 US gallon = +10 ppm magnesium 1 mL per 10 US gallons = +1 ppm magnesium\u003c\/p\u003e\n\u003cp\u003eDose safely: Do not increase magnesium by more than 50–100 ppm per day. Add dose gradually into a high-flow sump or display area.
