Other marine salts are simply blended in cement mixers using the bare minimum of ingredients. A poor mixing quality is the result because of the equipment and its inability to blend the fine particles in synthetic sea salt. There are but a few companies in the world that have the experience and the knowledge to produce a truly high quality marine salt. Elements like calcium and specific trace elements are fortified to enable captive marine animal to thrive in a closed system. M.E.I. commits to the evolution and the knowledge achieved in all fields of marine research and will continue to commit to the inclusion of this knowledge in all its products.
Marine salts vary greatly in calcium content.
Corals and some invertebrates require calcium levels over 400 ppm in closed systems such as those in home and commercial aquariums. Salts that are recommended for reef aquariums should contain calcium levels of 410 to 420 ppm. If you are uncertain about the calcium content of you salt, measure it after mixing, allowing about one hour for complete solubility. If the calcium level is over 400 ppm, you will notice a slightly longer dissolving time than salts with insufficient calcium levels. The time required for complete solubility is well worth the increased calcium levels your reef animals require.
