Seachem Reef Advantage Magnesium

A highly concentrated magnesium supplement designed to maintain optimal magnesium levels in reef aquariums.

Seachem Reef Advantage Magnesium is a premium dry magnesium supplement formulated to restore and maintain natural seawater magnesium levels in reef systems. Magnesium plays a critical role in stabilising calcium and alkalinity levels, helping prevent unwanted calcium carbonate precipitation and ensuring corals can efficiently utilise calcium for skeletal growth.

Maintaining proper magnesium levels is essential for healthy reef chemistry, particularly in aquariums with high coral demand. Reef Advantage Magnesium dissolves quickly and is ideal for regular dosing to maintain stable parameters in SPS, LPS, and mixed reef systems.

Suitable for all marine reef aquariums containing corals, clams, and other calcium-consuming invertebrates.
