Coral Pro Salt Premium grade, high Alkalinity Red Sea Coral Pro Salt contains raised levels of the foundation elements (Calcium, Magnesium, Bicarbonates) necessary for sustainable & accelerated coral growth. If you are aiming to increase coral growth, then Coral Pro combined with Red Sea’s reef care programs will increase growth by up to four times their natural rate. Coral Pro’s Alkalinity of 12 dKH makes it ideal for mixed reefs and SPS frag tanks. Natural seawater includes over 70 chemical elements, although 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 which are Calcium, Magnesium, and Bicarbonates. These three ‘foundation elements’ have a major effect on Alkalinity, pH stability, seawater ionic strength, and many of the coral’s biological processes (skeleton formation, ion-exchange, photosynthesis). Early 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 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.
