Why would you even say "I think" when you aren't really sure? Google is always a good way to go first when it comes to saying something like this.I wrote "I think maybe You ruined the tank with putting silicon grease on the seals."
I never suggested that the grease should solve the silicone seams. I suggested it might creep in between the seams and the glass.
What I should have wrote is that it is easy to check. If You can lift the seams the smallest bit with Your finger nails then my fear was correct.
If the seams sits OK then my theory was wrong. Easy to find out.
