Blue Treasure SPS Sea Salt is supplemented with magnesium (Mg), potassium (K), and other trace minerals to ensure adequate essential elements for marine life, promoting their survival and assisting in SPS coral breeding.
This product is manufactured under strict processes in accordance with ISO9001:2008 standards. Unlike other industrial salts, the sodium chloride in Blue Treasure Salt is purified from pure, non-polluted underground brine. This rare brine source is found only in the Bohai Bay and Huanghai Bay regions. These natural resources enable the production of some of the world’s finest sodium chloride.
Since 1966, the Ocean University of China has collaborated with Blue Treasure, providing scientific research to ensure the highest quality sea salt. All raw materials in Blue Treasure synthetic sea salts are pure, food-grade, and include all trace elements found in natural seawater. Additionally, special vitamins and protective colloids are added to enhance the immune functions of marine organisms.

Directions for Use
Mix 1 kg of Blue Treasure SPS Sea Salt with 28.5 liters (7.5 gallons) of fresh water (RO water recommended).
Stir until the salt completely dissolves.
Ensure the water temperature is between 23–25°C (73–77°F) and the specific gravity is between 1.024 and 1.026.
For optimal water quality, perform weekly partial water changes. Replace 10% of the total water volume with saltwater prepared using Blue Treasure SPS Sea Salt. This ensures the health and longevity of your marine organisms.
