Tropic Marin Pro-Reef Marine Salt

The pharmaceutical grade sea salt specially formulated for modern reef aquaria offers an optimized blend to support the delicate balance required for thriving marine ecosystems.

This premium sea salt is designed to meet the unique needs of reef tanks by providing enhanced concentrations of calcium and magnesium, essential elements that promote healthy coral growth. Its carefully balanced lower buffering capacity and correct pH value help stabilize natural water parameters, particularly maintaining carbonate hardness even when using calcium reactors.

Achieving natural and stable conditions for sensitive marine life depends on accurately balancing all influencing factors, and this sea salt delivers just that. It serves as the ideal foundation for the care and growth of fish, corals, and other aquatic invertebrates in contemporary reef aquariums. Whether performing regular water changes, starting a new aquarium, or re-equilibrating tank pH, seawater prepared with this salt ensures optimal living conditions. Benefits include:

• Optimized calcium and magnesium concentrations alongside balanced alkalinity and pH.
• Specifically formulated to satisfy the higher calcium demands of modern reef systems.
• Compatible with calcium reactors and mineral additive use.
• Maintains alkalinity within a 7-8° dKH range.
• Manufactured from pure, pharmaceutical-grade salts for superior quality.
• Contains all major and minor elements in exact proportions found in tropical seawater.
• Features 70 fully soluble trace elements through an advanced mixed-crystal production method.
• Produced under stringent pharmaceutical quality controls to ensure nature-identical seawater.
• Free from nitrates, phosphates, and other unwanted chemicals.

How to use:
To reach a salinity level of 32-35 ‰ (psu), dissolve approximately 35 ml of this sea salt per liter (or about ½ cup per US gallon) of RO/DI water at 73-77°F (23-25°C) while stirring. Always add salt to water to avoid calcium carbonate precipitation. Once nearly all salt is dissolved and the solution is clear, measure specific gravity with a hydrometer and adjust until reaching 1.025 to 1.027 (at 73-77°F). The pH should be between 8.0 and 8.4 for optimal use. After setting up a new aquarium, allow several weeks for biological stabilization under proper circulation and lighting. Regular weekly partial water changes, replacing about 10% of the total volume with this sea salt-prepared seawater, help maintain the water quality essential for the health of your marine livestock. Parameters: Approximate carbonate hardness of 7° KH, calcium around 440 ppm, and magnesium near 1350 ppm.
Application: Ideal for reef tanks with elevated calcium requirements and effective for maintaining alkalinity, especially when using calcium reactors. For convenient salt dosing, use the available dosing calculator to determine the precise amount needed for your aquarium.
