Hmmmm, I also question this process... Water evaporation doesn't remove salt, so if you top up with salt, you would be adding more salt. So I am a little confused that your Salinity doesn't change for the worse.

I would personally not do that, as I think it will eventually catch up to you, quicker than you think. Unless you have some sort of salt monster that eats salt.
