Sera Marin Basic Salt – Reef-Grade Sea Salt for Marine Aquarium Excellence

Sera Marin Basic Salt is a biologically balanced, premium-grade sea salt formulated for marine aquarium environments. Engineered for fast dissolution, it leaves zero residue and transforms RO or tap water into crystal-clear saltwater suitable for reef tanks, fish-only systems, or coral propagation setups.

Its composition mirrors natural ocean water with ideal general hardness (GH), carbonate hardness (KH), and elevated calcium and magnesium levels that support coral growth, calcifying invertebrates, and overall reef resilience. Free from synthetic additives and enhanced with 70 trace elements, it nurtures vibrant marine life and stabilizes aquatic chemistry.

Usage Instructions:

• Dissolve required quantity in RO or dechlorinated freshwater outside the tank
• Aerate for 15–30 minutes to ensure complete mixing
• Adjust salinity with hydrometer or refractometer before tank dosing
• Use in new setups or regular water changes to maintain ionic balance
