If the aquariums organisms are from brackish environments with lower salinity, or from the Red Sea with higher salinity, selecting something other than 35 ppt may make good Salinity conversion helps in converting different units of Salinity. An electrical current is passed between two electrodes immersed in water, and the higher the salinity, the more readily the current will be conducted (the ions in seawater conduct electrical currents). However, the EC of soil water depends on the soil to water extraction ratio, i.e., ECsw varies with soil water content and it is not a single number. ppt (%) stands for salinity percentages and ppt stands for parts per thousands.
