Coral Pro Salt is ideal for reef aquariums, in particular for LPS and SPS corals, and for growing coral frags. Natural seawater includes over 70 chemical elements and although most of the elements influence the water parameters, a few of them have a more significant role in its overall chemical stability. These elements form the foundation of the reef environment and they include the three major elements: calcium, magnesium and bi-carbonates. These three foundation elements have a major effect on the water chemistry (pH stability, alkalinity, seawater ionic strength) and on many of the corals biological processes (skeleton formation, ion- exchange, photosynthesis).
