Where to Buy TMC Reef Salt

Trusted by marine aquarists around the world, TMC Reef Salt is a premium-grade synthetic sea salt designed specifically for reef tanks. Developed by Tropical Marine Centre (TMC), a UK-based company with over 50 years of marine husbandry expertise, this salt mix is crafted to deliver consistent, reef-safe water chemistry with every batch. Whether you’re starting your first nano reef or maintaining a mature SPS system, you can order TMC Reef Salt directly from Pacific Fish Depot for fast, secure delivery.

What Sets It Apart

TMC Reef Salt stands out because of its pharmaceutical-grade composition and stability across core parameters. Every bucket or bag is blended in ISO 9001-certified facilities and batch-tested for quality assurance. It’s formulated to replicate natural seawater, providing the optimal balance of calcium, magnesium, alkalinity, and trace elements necessary for vibrant coral growth and coloration.

The mix is especially tailored for modern reef aquariums, offering slightly elevated levels of calcium (around 430 ppm), magnesium (1300–1350 ppm), and alkalinity (8–9 dKH), supporting stony coral development and healthy skeletal formation. Unlike many generic sea salts, TMC Reef Salt is low in nitrates and phosphates, minimizing the risk of algae blooms and promoting water clarity.

Easy Mixing, Reliable Results

This salt dissolves quickly in RO/DI water, producing clean, crystal-clear saltwater in under 30 minutes. There’s no foaming or residue, and the parameters remain stable, which is a key factor for reef keepers trying to avoid swings in pH or alkalinity. The result is a trustworthy base for any reef system, from soft coral lagoons to SPS-dominant aquascapes.

TMC Reef Salt is ideal for weekly water changes, tank cycling, and even coral quarantine systems. It’s gentle enough for sensitive species like acropora and clams, yet robust enough to support fish-only-with-live-rock (FOWLR) systems. And because of its clean profile, it requires little to no conditioning before use—just mix and aerate.

Industry-Trusted and Proven

TMC’s credibility as a brand is well documented. Their reef systems and salt mixes are used in commercial coral farms, aquaculture facilities, and high-end aquascaping setups across Europe and beyond. According to Practical Fishkeeping Magazine, TMC Reef Salt consistently ranks among the most trusted and scientifically backed salt products available, making it a favorite in both retail and professional reef environments.

Tips for Use

Use approximately 1/2 cup of salt per gallon (around 38–40 grams per liter) to achieve a specific gravity of 1.025. For best results, mix in a clean container using a powerhead or airstone. Allow saltwater to circulate for 1–2 hours before use. Always test salinity, pH, alkalinity, and temperature prior to adding to your tank.
