Halcyon Marine Reef Salt Mix is a high-purity synthetic sea salt designed to precisely match the inorganic composition of natural seawater. Manufactured in small batches in Continuum’s own facility, this 20kg mix uses only pharmaceutical and reagent-grade ingredients, ensuring consistent quality without relying on desalination by-products or waste materials. Developed over decades of marine chemistry research and salt mix production, Halcyon provides balanced parameters to support the health and growth of reef livestock. It delivers ideal conditions for keeping and propagating stony corals, especially small polyped stony (SPS) species, as well as other invertebrates and marine fish. When mixed as directed, the salt achieves a salinity of 35 ppt (specific gravity 1.026 g/cm³), with a stable pH of 8.3, alkalinity of 7.5 dKH, calcium at 415 ppm, and magnesium at 1,290 ppm. It is also suitable for marine and brackish systems when adjusted to species requirements. Key Features: Matches natural seawater inorganic chemistry Uses pharmaceutical and reagent-grade ingredients only No desalination waste or by-products Stable, reef-safe levels of calcium, magnesium, and alkalinity Ideal for SPS corals, invertebrates, and marine fish Produced in-house with tight quality control This 20kg pack of Halcyon salt mix provides excellent value and performance for reef aquarists who require stability and precision in water chemistry for thriving coral systems.
