Fauna Marin Balling Salts Biopolymer Magnesium Mix is a laboratory-grade, ultra-pure specialty salt designed for the precise management of magnesium levels in marine reef aquariums. Functioning as the magnesium component in the globally recognized Balling Light System, this formulation is unique because it is infused with Organic Peptide Polymers (Biopolymers), bioactive stabilizers, and pH buffers. These proprietary organic additions prevent chemical parameter fluctuations, increase the structural stability of the water column, and optimize element availability so corals can easily absorb minerals without expanding unnecessary metabolic energy, completely preventing the darkening of delicate coral tissues.
This specialized biopolymer-enriched mix provides a superior approach to foundational reef chemistry compared to generic, unbuffered magnesium salts.
Organic Peptide Polymers: Acts as a natural carrier matrix that ensures macro and trace elements stay stable in solution, enhancing biological usability by corals, fish, and filtering bacteria.
No Magnesium Sulfate Required: The modernized Balling Light recipe completely eliminates the need for messy magnesium sulfate additions, keeping your mixing routine straightforward and reducing unnecessary ionic drift.
Prevents Coral Darkening: High-purity pharmaceutical-grade processing combined with bioactive stabilizers preserves natural coral coloration and prevents the tissue "browning" often triggered by impurities.
Optimized for Modern Salts: Engineered to integrate seamlessly with high-performance synthetic salt mixes and heavy LED lighting setups where element consumption is accelerated.
System Compatibility: Functions flawlessly alongside all common filtration strategies, including Zeolite methods, traditional Berlin systems, or natural macro-algae mud filters.

Why are there biopolymers in this magnesium mix?
Fauna Marin adds Organic Peptide Polymers to act as stabilizers. They increase the chemical stability of the parameters in your aquarium and serve as a transport mechanism, making the macro-elements more accessible to coral polyps.
Do I add Trace 1, 2, or 3 to this container?
No. Under the updated Fauna Marin Balling Light instructions, the Magnesium Mix canister is kept completely pure. The Trace 1 and 2 metallic concentrates are added to your Calcium canister, while Trace 3 belongs in your Carbonate/Alkalinity canister.
What happens if my Magnesium drops too low?
If magnesium drops below 1200 mg/L, your calcium and alkalinity will lack the chemical scaffolding to remain dissolved in liquid form. You will experience heavy precipitation, leading to a drop in alkalinity and calcium scaling on pumps and heaters.
How should I space out my doses?
Always start by dosing your Magnesium solution first, followed by Calcium, and lastly Carbonate/Alkalinity. Ensure there is a minimum interval of 10 minutes between each automated dose to prevent localized precipitation in the sump.
