Halcyon Marine Reef Salt Mix by Continuum is a premium-grade synthetic sea salt formulated to match the complete inorganic profile of natural seawater. Manufactured in small batches under stringent in-house quality controls, this mix is made entirely from reagent and pharmaceutical-grade ingredients—never from desalination waste or residues.

Backed by decades of marine chemistry expertise, Halcyon delivers consistent parameters that support the health and propagation of reef organisms, particularly small polyp stony (SPS) corals. It is suitable for use in both reef and brackish water systems, with salinity adjustable to meet specific needs.

When mixed as directed, Halcyon provides a salinity of 35 ppt (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—ideal conditions for sensitive reef livestock.

Key Features:

• Formulated to replicate full seawater inorganic chemistry
• Pharmaceutical and reagent-grade ingredients only
• Consistent calcium, magnesium, alkalinity, and pH levels
• Manufactured in-house with tight quality control
• Ideal for SPS corals and sensitive reef species

This salt mix is a reliable choice for aquarists demanding high-quality, stable seawater conditions for coral growth and overall reef health.
