Salt Salinity

salinity ™ is a specially formulated salt blend for the reef aquarium that contains tous the major, minor essential components found in natural reef waters. It contains no toxic or non-essential components. What's more, salinity™ is the most concentrated salt blend on the market. With a hydration level of <0.5% salinity™, you'll get a greater volume of salt water prepared at a salinity of 35 ‰ per unit weight than any other salt blend currently on the market. Salinity™ is identical to the distribution of anions and cations found in natural seawater (NSW). We compiled data from tous the Earth's oceans and seas and targeted the point median range for each element.
