AquaPro Reef Magnesium is a high-purity, ammonia-free magnesium supplement that supports stable magnesium, calcium, and alkalinity levels in reef aquariums.
AquaPro Reef Magnesium is a high-purity powdered magnesium supplement formulated to safely raise and maintain magnesium levels in marine and reef aquariums. Magnesium is essential for normal coral growth and helps stabilize calcium and carbonate chemistry.
Low magnesium can make it difficult to maintain appropriate calcium and alkalinity because calcium carbonate may precipitate more readily. Regular testing and controlled supplementation help maintain a balanced reef environment.
The formula contains no added ammonia.
