It has been an issue since day one on this tank & I can't figure it out either. There are no leaks as I check weekly so the wife doesn't freak out. I do have several bad spots of salt creep that drive me crazy & will be addressing with the new tank set up. My skimmer does skim some what wet but I still haven't been able to get it tuned just right, it's a Deltec 702 external recuculating skimmer so not a cheap one.
