I actually do check my salinity every few days and adjust the salinity of the top off water accordingly. I have been doing it this way for three years and it gets predictable. For instance after a heavy feeding, I can expect the skimmer to be more active and I would add more salt to the top off container. Not hard to do and I feel that wet skimming has helped control my nitrates.

Yes, all my top off is salty water.
