High-Purity Single Element Supplementation
Part of the completely revisedATI® ICP Elementslineup, this high-purity magnesium solution is designed for the precise adjustment of element levels in reef aquariums. Developed and tested in the ATI® Lab in Germany, these solutions are ideal for both compensating acute deficiencies and maintaining daily element supply to ensure a stable chemical environment and healthy coral growth.
Why Magnesium (Mg) is Essential
Magnesium is a major element in seawater and is critical for maintaining the chemical balance of your reef. Its primary role is to prevent the abiotic precipitation of calcium and alkalinity.
-
Chemical Stability:Magnesium allows for high concentrations of calcium and carbonate to coexist in the water. At low magnesium levels, alkalinity and calcium can precipitate, making it difficult to maintain stable parameters.
-
Skeletal Development:It is essential for the growth of stony corals. Without it, growth slows significantly and coral skeletons can become brittle.
-
Refugium & Algae:Magnesium is a core component of chlorophyll and is required for the growth of coralline algae.
-
Coral & Invertebrate Health:Low levels can lead to the degeneration of soft corals and affect the shell development of snails and other mollusks.
-
Common Causes of Deficiency:High consumption by calcifying organisms (SPS and coralline algae), precipitation due to chemical imbalances, or the use of salt mixes with insufficient magnesium concentrations.
