Seachem magnesium reef supplement is a 300g container of balanced magnesium chloride and magnesium sulfate powder formulated to restore and maintain optimal magnesium levels in marine reef aquariums. This standard home-use size provides the perfect amount of magnesium powder for typical reef hobbyists who need regular magnesium supplementation without purchasing the larger professional containers. Magnesium is a critically important but often overlooked parameter in reef aquarium chemistry sitting alongside calcium and alkalinity as the third essential element of the reef chemistry triad. When magnesium falls below the optimal range of 1250 to 1350 parts per million the entire calcium and alkalinity system becomes unstable because magnesium acts as a natural inhibitor of spontaneous calcium carbonate precipitation. Without adequate magnesium calcium and alkalinity will continuously drop despite supplementation as they precipitate out of solution onto rocks substrate and equipment surfaces. This frustrating problem is one of the most common hidden causes of poor coral growth and unstable water chemistry in reef aquariums. The seachem magnesium reef supplement solves this problem with a scientifically balanced blend of magnesium chloride and magnesium sulfate that maintains the natural seawater ratio between these two magnesium salts. This balanced approach prevents gradual ionic ratio drift that can occur when using only magnesium chloride which would slowly elevate the chloride to sulfate ratio beyond natural seawater values. The dry powder format is highly concentrated allowing precise dosing by weight and providing excellent value compared to liquid magnesium products. Each gram raises magnesium by a predictable amount making accurate dosing calculations straightforward. The 300g container provides weeks of regular magnesium supplementation for medium-sized home reef aquariums. Available at TaraPet the UAE trusted online pet and aquarium store with free delivery.
