Red Sea Sea Salt is formulated to provide the precise parameters of natural tropical reef water, with a slightly elevated alkalinity to support the unique demands of a closed marine system. Harvested directly from the pristine waters of the Red Sea, this all-natural, eco-friendly salt mix ensures your aquarium receives a biologically balanced foundation. It is engineered for stability and consistency, making it an excellent choice for establishing and maintaining a healthy aquatic environment for a wide range of marine life.

This premium salt mix delivers balanced levels of foundation elements including calcium, magnesium, and carbonates, along with a full complement of essential trace elements. Guaranteed to be free of nitrates, phosphates, and toxic heavy metals, it promotes a clean, algae-free environment. Red Sea Salt contains no chemical binders and has a low moisture content, ensuring every batch is pure and dissolves quickly to produce stable seawater with a pH between 8.2 and 8.5 when mixed with RO water.

Ideal for both novice and advanced hobbyists, Red Sea Salt is particularly well-suited for fish and invertebrate systems, as well as low-nutrient SPS dominant tanks where meticulous control over individual element supplementation is desired. Whether you are maintaining a fish-only tank at 30 ppt, an ultra-low nutrient system at 33 ppt, or a thriving SPS dominant reef at 35 ppt, this salt provides the perfect baseline for success, allowing you to replicate the conditions of a natural coral reef in your home aquarium.
