Natural seawater contains more than 70 chemical elements. Most of them influence water parameters, but only a few play a significant role in its overall chemical stability. These elements form the foundation of the reef environment and include three major elements: Calcium, Magnesium and Bicarbonates.

These three "Basic Elements" have a major effect on the stability of pH, alkalinity, ionic strength of seawater and many biological processes of corals (skeletal formation, ion exchange, photosynthesis) .

Unlike the natural environment, where there is a huge reservoir of Fundamental Elements, the reef aquarium has limited resources that are quickly depleted by the inhabitants of the aquarium. Therefore, in order to allow sustainable growth of corals, it is necessary to maintain higher levels of Fundamental Elements than in the natural environment.

Early research conducted in the Red Sea laboratory has shown that when levels of the Fundamental Elements are increased above those of the natural environment, a very specific ratio between the Fundamental Elements is required for the vitality of the coral, and the formation of a robust aragonite skeleton.

Red Sea Salt is made to these ideal ratios, eliminating the need to over-adjust Fundamental Element levels after water changes and allowing corals to enjoy a healthy and stable environment.
