MAGNESIUM CHLORIDE 4 Kg – High Purity Magnesium Chloride for Marine and Reef Aquariums
Magnesium Chloride 4 Kg is a professional-grade technical additive designed for precise magnesium adjustment in large marine aquariums and high-demand reef systems. Magnesium is essential for the growth of hard corals (SPS and LPS), coralline algae, and for maintaining a balanced ionic environment. Ideal magnesium levels range from 1300 to 1400 ppm, supporting overall reef health and chemical stability.
With pharmaceutical-grade purity (minimum 99.6%), this magnesium chloride dissolves completely in RO water without leaving any residue. The 4 Kg format is ideal for public aquariums, commercial systems, or advanced reef keepers who need long-term and reliable supplementation, including use with dosing pumps.
