Triton Magnesium Chloride is a high-purity Magnesium Chloride Hexahydrate (MgCl26H_2O) designed for the precise adjustment of magnesium levels in marine reef aquariums. Part of the Triton "DIY" chemical range, this pharmaceutical-grade salt is lab-tested and quality-controlled to ensure it is free from contaminants like phosphates and heavy metals. Magnesium is one of the "Big Three" parameters in a reef tank; it acts as a chemical buffer that prevents the premature precipitation of calcium and alkalinity. By maintaining natural magnesium levels, aquarists ensure that essential minerals remain bioavailable for coral calcification and coralline algae growth.
Triton MgCl_2 provides a clean, cost-effective way to manage large-scale ionic corrections or to build your own custom dosing solutions.
Laboratory Certified Purity: Every batch is tested at the Triton Lab to guarantee the highest quality and safety for sensitive reef inhabitants.
Essential Chemical Buffer: Prevents the "snowing" effect of calcium carbonate by keeping calcium and carbonates in solution.
Bulk Format Efficiency: The 4 kg size is ideal for larger systems or for those mixing bulk quantities of 2-part or 3-part dosing solutions.
Total Control: Allows you to adjust magnesium levels independently without affecting other macro-elements or shifting your salinity balance toward sodium.
Supports Calcification: Directly contributes to the health of SPS, LPS, and soft corals by providing the minerals necessary for skeletal integrity and metabolic function.

How do I prepare the solution?
Dissolve the required amount of dry powder into RODI water. Once the salt is fully dissolved and the liquid is clear, slowly add the solution to a high-flow area of your sump or display tank.
Can I use this with the Triton Method?
Yes. While the Core7 Base Elements provide daily maintenance, this salt is used for the initial "adjustment phase" to bring your magnesium to the baseline recommended by your ICP-OES analysis.
Why is Magnesium important for my Alkalinity?
If magnesium is too low (below 1200 mg/L), you will struggle to keep your Alkalinity stable. Magnesium molecules "blind" the surface of calcium carbonate crystals, preventing further crystal growth and keeping the elements liquid.
Does this product contain any Magnesium Sulphate?
This specific product is pure Magnesium Chloride. If you are following a traditional Balling Method that requires a specific ratio of Chloride to Sulphate, you should dose them accordingly; however, for the Triton Method, MgCl_2 is the primary salt used.
Triton ICP-OES Water Test: The essential diagnostic tool to determine exactly how much MgCl_2 you need to dose based on your current levels.
Triton Calcium Chloride (CaCl_2) 4kg: The corresponding macro-element for coral skeletal growth, often used alongside magnesium increasers.
Triton Sodium Bicarbonate (NaHCO_3) 4kg: The alkalinity-boosting salt required to complete the "Big Three" foundational minerals.
