Salinity is a measure of the total amount of dissolved salts in seawater. It is measured in parts per thousand (ppt or 0/00). The average salinity of the ocean is around 34 to 37 ppt. Marine aquariums are measured in specific gravity. Specific gravity may be defined as the ration of the density of the liquid to the density of water. The specific gravity of seawater at 35 ppt is 1.026. The proper range for a marine aquarium is 1.020 to 1.026.
