Tropic Marin Bio-Magnesium is a biologically ideal crystalline powder supplement designed to replenish essential magnesium in marine reef aquariums. Magnesium is a major constituent of natural saltwater and is critical for coral skeletal formation, coralline algae growth, and biochemistry—including photosynthesis. Adding plain magnesium salts can disrupt the delicate ionic balance of your aquarium. Bio-Magnesium prevents magnesium deficiency while maintaining a perfect ionic balance and delivering carbon dioxide ($CO_2$) to support photosynthesis.
Key benefits
Promotes Photosynthesis: Supplies biologically available carbon dioxide ($CO_2$) to aid in the photosynthesis process of zooxanthellae.
Balanced Mineral Formula: Replenishes magnesium without disrupting the critical ionic balance of your seawater.
Accelerates Coral Growth: Essential for the skeletal development of reef-building corals and coralline algae.
Pure Quality: Completely free of phosphates, nitrates, and other unwanted synthetic byproducts.
Restores Deficiencies: Easily raises magnesium levels back to natural coral reef concentrations of 1280–1300 ppm.
Specifications
Net weight: 16 oz (approx. 450 g)
Form: Crystalline powder
Primary purpose: Ionically balanced magnesium and mineral supplementation
Intended users: Marine reef keepers, coral aquascapers, and advanced hobbyists
Suggested use
Direct application: Sprinkle the powder directly onto the surface of the water in a high-flow area of your aquarium, such as near a pump or return.
Dissolve before contact: Ensure the powder dissolves fully in the water column before it can settle directly onto corals or invertebrates.
Stock solution option: Can also be mixed with RO/DI water to create a liquid magnesium dosing solution.
Dosage and testing
Standard Dose: One level measuring spoon (included) increases the magnesium level of 30 US gallons (110 liters) of water by about 10 ppm.
Maximum Daily Dose: Do not exceed 2 measuring spoons per 30 US gallons (110 liters) of aquarium water per day.
Target Levels: Keep magnesium levels between 1280–1300 ppm. Do not exceed 1600 ppm, as excessively high concentrations can harm reef inhabitants.
Storage and safety
Store in a cool, dry place with the container lid tightly sealed against humidity and moisture.
Keep out of reach of children and pets.
First Aid: If powder makes contact with eyes, rinse thoroughly with clean water.
Warnings
Not for human consumption.
Monitor specific gravity regularly when dosing, as adding minerals can slowly increase salinity over time.
Do not apply powder directly on top of corals or sessile invertebrates.
What’s included
1 x 16 oz container of Tropic Marin Bio-Magnesium Powder
1 x Measuring spoon
Product label with usage instructions
Why choose
Tropic Marin Bio-Magnesium offers a biologically optimized solution for keeping magnesium levels stable without risking the chemical stability of your marine tank. It delivers both vital magnesium and a photosynthesis boost through balanced carbon dioxide release, making it much more effective than standard single-compound additives. This 16 oz container is a highly cost-efficient size for nano and mid-sized reef systems.
