Skimmer Salinity Drop Calculator
This calculator estimates the drop in salinity brought about by removing saline skimmate from a system in which the lost water volume is replaced entirely with freshwater. This salinity drop is typically negligible except when wetskimming is employed; for example, as a mechanism for waterchange.
It is not necessary to take into account evaporation of the skimmate while in the skimmer collection cup. As the skimmate volume decreases by evaporation, it's salinity will increase proportionally.

* Note that neither a hydrometer nor a refractometer is a good choice for measuring the salinity of skimmate, especially thick skimmate. A conductivitymeter should be used to take this measurement.
