Instant Ocean Sea Salt is a widely used, synthetic marine salt mix for fish-only and reef-capable aquariums, formulated to closely mimic natural seawater and provide essential major, minor, and trace elements required for healthy marine life.
Key Features:
Fast Dissolving & Clear Solution Rapidly dissolves within minutes, yielding crystal-clear water—and it’s nitrate- and phosphate-free.
Consistently Formulated Each batch is carefully blended to ensure reliable quality, supported by over 40 years of use in aquariums and research facilities.
Fish- & Reef-Capable Suitability Provides a sound basic foundation for fish-only, FOWLR (fish-only, with live rock), and light coral systems; many reef-keepers supplement further for hardier coral requirements.
Easy Mixing Guidelines Use ½ cup per gallon (~345 g/10 L) to reach ~30 ppt, or 1.5 cups per gallon (~390 g/10 L) for ~33 ppt; mix in purified or dechlorinated water and aerate for 5–15 minutes.
Wide Range of Packaging Sizes Available from small consumer buckets to large-scale 60-lb (200-gallon capacity) bags for economical water changes.
