Fauna Marin Elementals Mg Magnesium 1000ml
Essential Magnesium for Stable Reef Chemistry & Healthy Coral Growth
Fauna Marin Elementals Mg is a concentrated liquid magnesium supplement developed to maintain stable magnesium levels and support balanced calcium and alkalinity in marine reef aquariums.
Magnesium plays an essential role in seawater chemistry, helping prevent excessive calcium carbonate precipitation and allowing calcium and alkalinity to remain available for coral skeletal development.
As reef aquariums mature, magnesium can be consumed by corals, coralline algae and other marine organisms. Maintaining appropriate concentrations helps create stable conditions for healthy coral growth.
Key Features & Benefits
-
Maintains magnesium levels – Replenishes magnesium consumed by reef organisms.
-
Supports calcium stability – Helps reduce unwanted calcium carbonate precipitation.
-
Promotes healthy calcification – Maintains favourable conditions for coral skeletal growth.
-
Supports coralline algae – Provides an important mineral used by calcifying marine organisms.
-
Balanced reef chemistry – Helps maintain stable calcium and carbonate concentrations.
-
Suitable for SPS & LPS reefs – Ideal for established mixed reef aquariums.
-
Ready-to-use liquid – Convenient supplementation without mixing powders.
-
1000ml bottle – Practical for regular reef aquarium maintenance.
Recommended Dosage
100ml per 100 litres increases magnesium by approximately 100ppm (100mg/L).
Maximum daily adjustment: Do not increase magnesium by more than 100ppm per day.
Fauna Marin recommends maintaining magnesium between 1300–1350ppm at a salinity of 35ppt.
Always test magnesium levels before supplementation and calculate the required dose using your aquarium's actual water volume.
Why Maintain Magnesium?
Magnesium is one of the major elements found in natural seawater and is essential for maintaining balanced reef aquarium chemistry.
Insufficient magnesium can make calcium and alkalinity more difficult to maintain, potentially affecting coral calcification and overall aquarium stability.
Regular water changes may provide sufficient magnesium for some aquariums, while heavily stocked reef systems may require additional supplementation.
Complete Your Reef Supplementation Routine
For comprehensive reef maintenance, combine Elementals Mg with suitable Fauna Marin calcium and alkalinity supplements.
We also recommend a magnesium test kit to monitor consumption, alongside calcium and KH testing for a complete picture of your aquarium's water chemistry.
For convenient daily supplementation, consider adding a reliable dosing pump to your reef maintenance equipment.
Fauna Marin Elementals Mg – reliable magnesium supplementation for balanced reef chemistry and thriving corals.
