Red Sea Red Sea Salt is specially formulated with moderately elevated and precisely balanced levels of the three essential foundation elements—Calcium, Magnesium, and Bicarbonates—to support sustainable coral growth and vibrant coloration. With an alkalinity of 8 dKH, it is ideal for all reef aquarium types, especially SPS-dominated systems. When used alongside Red Sea’s Reef Care Recipes, Red Sea Salt enhances pigment saturation and promotes coral growth at rates up to twice those found in nature.

Natural seawater contains over 70 elements, but only a few—primarily the foundation elements—are critical to maintaining chemical stability and supporting vital biological functions such as pH balance, ion exchange, photosynthesis, and skeletal development. In a closed reef system, these elements are quickly depleted, making elevated and well-balanced supplementation essential. Based on original Red Sea research, Red Sea Salt is blended to match the optimal ratio of these elements, eliminating the need for post-water-change adjustments and creating a stable, healthy environment for coral vitality and robust aragonite skeleton formation.
