Red Sea Coral Pro Salt 22kg

Red Sea Coral Pro Salt is a premium-grade marine salt mix engineered for reef aquariums, offering elevated and balanced levels of the “foundation elements” — calcium, magnesium and bicarbonates — that corals need for healthy skeleton growth, strong skeletal structure, and vibrant coloration.

When mixed with RO/DI water, Coral Pro delivers a stable, reef-optimized seawater formula: alkalinity around 12 °dKH, calcium typically ~435–465 mg/L, and magnesium ~1310–1390 mg/L (depending on final salinity) — parameters ideal for mixed reefs, SPS/LPS corals, and frag systems. 

This salt mix is free from nitrates and phosphates, contains no chemical binders, and has low moisture content, making mixing quick and clean (dissolves in as little as ~20 min), with minimal need for adjustment before water changes. 

Because Red Sea Coral Pro includes a full complement of trace and minor elements — along with the foundation elements — it helps maintain overall ionic balance, supports healthy coral metabolism, and reduces the need for frequent macro-element dosing after every water change.
