Red Sea Coral Pro Salt – 55 Gallon

Support coral growth with Red Sea Coral Pro Salt, a premium reef salt mix formulated with elevated levels of calcium, magnesium, and alkalinity for reef aquariums with growing corals.

Coral Pro is designed for reef systems with a higher demand for foundation elements, making it especially well suited for SPS, LPS, mixed reef, and coral grow out systems.

The convenient 55-gallon bucket provides a manageable option for routine water changes without requiring the storage space of a large commercial-size salt container.

Elevated Foundation Elements

Coral Pro is formulated with elevated and biologically balanced levels of the three major foundation elements used by calcifying corals: calcium, magnesium, and carbonates.

When prepared to approximately 35 ppt salinity, Coral Pro targets approximately:

Calcium: 465 ppm
Magnesium: 1,390 ppm
Alkalinity: 12 dKH

These elevated parameters make Coral Pro particularly useful for reef aquariums with active coral growth and increased consumption of foundation elements.

Coral Pro vs. Red Sea Blue Bucket

Red Sea offers two primary salt formulations for different reef-keeping approaches.

Coral Pro Salt provides elevated calcium, magnesium, and alkalinity and is designed to support accelerated coral growth.

Red Sea Salt Blue Bucket provides more moderate foundation parameters closer to natural seawater levels and is well suited for reef keepers who prefer maintaining lower alkalinity or managing supplementation independently.

Choose the formula that best matches your aquarium's livestock, nutrient levels, dosing strategy, and desired water parameters.

Mixing & Use

Mix Coral Pro Salt with clean freshwater, preferably RO/DI water, following Red Sea's current mixing instructions.

Always test the salinity of newly prepared seawater before adding it to your aquarium and appropriately match temperature and salinity before performing a water change.

Because Coral Pro is formulated with elevated foundation elements, aquarists should consider the existing calcium, magnesium, and alkalinity levels of their aquarium when performing larger water changes.

Never add dry salt directly to an aquarium containing livestock.
