automatic top off
Automated system for adding water to an aquarium or sump in order to maintain a constant water volume. Particularly important in marine aquaria where salinity increases if water is allowed to evaporate without being replaced.
brackish
Refers to water with a salinity between that of freshwater and seawater, technically 0.5 - 30 grams of salt per litre, equivalent to 0.5 - 30 parts per thousand (ppt).

Of aquatic organisms, able to tolerate a wide range of salinity. Opposite of stenohaline.

refractometer
Instrument used to measure salinity or specific gravity via the refractive index (basically, the degree that light bends when shined through something) of a liquid. Most models are designed to measure sodium chloride or brine solutions and not seawater which contains a more complex range of salts and minerals, but usually more accurate than a hydrometer nevertheless.
salt bath
Treatment against various parasites which involves placing a freshwater fish in a solution of saline water with the salt concentration and period of exposure variable depending on the size of the fish and severity of infection. Similar to a salt dip in that parasites are killed via osmotic shock, but of longer duration.
salt dip
Treatment against various parasites which involves briefly placing a freshwater fish in a solution of saline water with the salt concentration depending on the size of the fish and severity of infection. Similar to a salt bath in that parasites are killed via osmotic shock, but of much shorter duration.
specific gravity
Ratio of the density of a liquid to the density compared with pure water. Often used to deduce the salinity of aquarium water and measured using a hydrometer or refractometer.
