Red Sea Salt contains moderately elevated and balanced levels of the foundation elements (Calcium, Magnesium, Bicarbonates) necessary for sustainable coral growth.

When combined with our reef care recipes, it will maximize pigment saturation to bring out your coral’s most vivid colors, while encouraging growth up to twice the natural rate. Red Sea Salt’s Alkalinity of 8dKH makes it ideal for all reef aquarium types, and especially SPS dominated tanks.

The three ‘foundation elements’ have a major effect on pH stability, Alkalinity, seawater ionic strength, and many of the coral’s biological processes (skeleton formation, ion-exchange, photosynthesis).

Unlike the natural reef environment, where there is an immense reservoir of the foundation elements, the reef aquarium has limited resources that are quickly depleted by the aquarium inhabitants. Therefore, in order to enable sustainable coral growth, it is necessary to maintain higher than natural levels of the foundation elements.

Original research carried out in Red Sea’s laboratory has shown that when increasing the levels of the foundation elements above the natural sea levels, a very specific ratio between the foundation elements is necessary for coral vitality, and the formation of a robust aragonite coral skeleton.

Red Sea Salt is made according to these ideal ratios, removing the need to adjust the levels of foundation elements after water changes, and providing your corals with a healthy and stable home.

Why use Red Sea Salt

Unlike the natural reef environment, which has an immeasurable reservoir of all 57 elements, a reef aquarium is an artificial environment that is constantly affected by coral growth and other ongoing biological processes.

The new formula of Red Sea Salt is the product of years of research into the physiological demands of corals in the reef aquarium. Hence, we recommend using a complete salt mix, which saves you money and time on testing supplies and major element adjustments.

Red Sea Salt is formulated for use with RO water.

Red Sea Salt vs Coral Pro Salt

Both Coral Pro Salt and regular Red Sea Salt use the same raw materials, including the unique Sodium Chloride harvested from the Red Sea reef, and both have optimally balanced ratios between the foundation elements.

However, the regular Red Sea Salt contains natural levels set for mature aquariums and enhanced coral colouration whereas the Red Sea Coral Pro Salt contains elevated levels of foundation elements set for accelerated coral growth.

Red Sea offers a premium sea salt mixture based on natural sea salt harvested from the waters of the exotic Red Sea by solar evaporation techniques. Red Sea Salt is enriched with other refined minerals to faithfully replicate natural seawater for your aquarium.

Used for over 10 years by hobbyists and professionals alike, Red Sea Salt has become famous for its favorable effect on invertebrates. Red Sea Salt is the only salt formulation offered today that is derived principally from a living sea.

Special Characteristics of Red Sea Salt:

•  A single, chemically balanced formula to support the most delicate marine life 
•  Suitable for marine fish and invertebrates from every sea and ocean
•  Reaches a stable, natural pH shortly after mixing 
•  No nitrates or phosphates 
•  Produced by a small batch process to ensure homogeneity of salt mixture 
•  Every batch is biologically and chemically tested for quality control
•  Suitable for a small water change or a complete new aquarium set-up
•  Can be mixed to any desired salinity 

1.4 lb dissolved in 5 gal of Reverse Osmosis (R.O.) water at 750F (1Kg dissolved in 30 liters at 250C) will produce a seawater solution as follows: Specific gravity 1.021 pH 8.4 (after 2 hrs mixing or aerating) Alkalinity 2.2-2.5 milliequivalents/litter.

One level cup of salt produces exactly 3.75 US gallons of seawater solution at a specific gravity of 1.021.
