Nyos Pure Salt Mix is a premium synthetic sea salt designed to produce ultra-clear, stable seawater for reef aquariums. Made with pharmaceutical-grade ingredients and rigorously ICP tested to ensure consistency, it delivers near-natural water parameters that support coral growth, color, and long-term stability.

Ultra-Clean Formula - Mixes Clear

Made with highly refined sodium chloride and premium calcium and magnesium compounds, Nyos Pure Salt minimizes unwanted impurities such as heavy metals and organic contaminants, helping maintain crystal-clear water and a healthier reef environment. It’s purity you can see when you mix it.

Verifiable Quality - ICP Tested

Every batch is ICP-tested, documented, and labeled to ensure consistency and quality, giving aquarists unmatched confidence and predictable alkalinity, calcium, and magnesium levels.

Fast Dissolving & Ready in Minutes

Thanks to its fine, homogeneous particle structure, the salt dissolves in about 5 minutes at room temperature, producing clear seawater you can use almost immediately without a long dissolving period.

Consistent Batch-to-Batch Quality

Each bucket is produced using a specialized mixing process used in the pharmaceutical and food industries, ensuring perfectly uniform composition from top to bottom with no separation or inconsistency during use.

Optimized for Reef Health

Formulated to closely match natural seawater levels, Nyos Pure Salt supports strong coral growth, polyp extension, and coloration while avoiding excessive nutrient or organic additives that can trigger algae or cyanobacteria issues.
