Product details
Seachem Reef Advantage Magnesium – 600g (633) is a concentrated magnesium supplement for reef aquariums. It provides an ionically balanced blend of magnesium with chloride and sulfate salts to help restore depleted magnesium levels while aiming to minimize disruption to the ionic ratios found in natural sea water. In practical terms, it’s used when aquarium magnesium drops—something that can happen after kalkwasser use or from carbonate additives that can drive magnesium into insoluble or slowly dissolving forms.
Features:
- Concentrated magnesium blend designed to restore depleted magnesium levels
- Optimized to help maintain natural-seawater-style ionic ratios
- Supplies magnesium with chloride and sulfate salts
- Contains no ammonia (a common contaminant in liquid magnesium supplements)
- Helps prevent ionic imbalance that can interfere with stable reef parameters
- Addresses magnesium depletion associated with kalkwasser and carbonate-additive precipitation effects
