Possible leak on silicon of Tank.

[jorjef]

If I slop water over the edge and it rolls down the front front glass and settles on/behind the trim before I can catch it I will have salt creep after the water evaporates. Pull back the trim back as best you can in the effected area, dry between the glass and trim . Watch it for the next day or two. If it reappears after you may have a leak, if not I wouldn't worry about it.
