Magnesium12+

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.

Directions / Mode d’emploi

DIRECTIONS
TEST

Calculate from current and target magnesium.

DOSE
