If I were to do this:
I would use a float switch in the nsw to stop the process if there is not enough water and possibly use a salinity probe to check the salinity or just manually check it with my refractometer every few days. The mix up water I use now barely evaporates (no salinity shift) covered 5 gallon bucket over a weeks time anyways so as long as the batch it the correct salinity it should be ok.
I would also use a temp probe and a heater to match exactly the dt temp.
