Use the following calculator to accurately determine how much salt mix you will need to add to adjust your aquarium to a specific salinity.

Note that we are using salinity (grams of salt per liter of water) rather than specific gravity which you will often encounter in retail stores. Salinity is simply easier to use in calculations, and it is not dependent on variables like pressure and temperature, making it the superior measurement for salt concentration in aquariums.
