Tropic Marin® Pro-Reef Sea Salt – Pharmaceutical-Grade Salt for Modern Reefs

Tropic Marin® Pro-Reef Sea Salt is a premium, synthetic sea salt specifically engineered to meet the high demands of modern reef aquariums. Manufactured from pharmaceutical-grade raw materials, it contains all 70 trace elements found in natural tropical seawater in their exact proportions. Pro-Reef is uniquely formulated with optimized concentrations of calcium and magnesium to support coral calcification, while its adjusted buffering system stabilizes $pH$ and alkalinity, making it the ideal foundation for delicate stony corals, invertebrates, and sensitive marine fish.

Optimized Chemistry & Superior Purity

Pro-Reef provides a stable, nature-identical environment that simplifies the maintenance of complex reef ecosystems.

Optimized Calcium & Magnesium: Provides approximately 440 ppm Calcium and 1350 ppm Magnesium to promote rapid coral skeletal growth and coralline algae development.
Controlled Alkalinity (7–8° dKH): Designed with a lower, more natural buffering capacity that is particularly suitable for systems using calcium reactors or specialized mineral additives.
Pharmaceutical-Grade Purity: Free from nitrates, phosphates, and other unwanted synthetic additives, ensuring you only add what your reef needs.
Mixed-Crystal Method: Ensures that all 70 trace elements are completely soluble and biologically available, preventing the "clumping" or precipitation common in lower-quality salts.
Exceptional Solubility: Dissolves quickly and clearly in RO/DI water, allowing for stress-free water changes without leaving behind residue or film.

FAQ Section: Common Questions
- How do I mix Tropic Marin® Pro-Reef? Always add the salt to the water, never water to the salt. Dissolve approximately 35 ml (37–40 g) per liter of RO/DI water at 23–25°C while circulating. The water is ready once it is completely clear.
- Is this salt suitable for fish-only tanks? While it can be used for any marine tank, Pro-Reef is specifically optimized for reefs with high calcium demands. For fish-only systems with higher alkalinity needs, Tropic Marin® Classic may be a more cost-effective choice.
- Can I store the mixed saltwater? Yes. Due to its high-purity pharmaceutical salts, the prepared saltwater can be stored for several weeks in a clean, circulated container before use without significant parameter shifts.
- Why is the alkalinity lower than some other brands? Pro-Reef targets a natural seawater alkalinity of 7–8° dKH. This prevents the risk of "alkalinity burn" in ultra-low nutrient systems and provides a stable baseline for those using dedicated dosing pumps or reactors.
