Wow. Looks great. My situation was not like that. So, red sea started putting armored seams across the bottom and the bubble I had was just the armored seem silicon detach from the glass, nonstructural so RS wouldn’t replace but offered a new tank at cost plus shipping. Or if it does become structural they would offer a replacement. After looking it over and talking to them, I agree with their assessment.
See the pic, the perfectly line where the armored seem ends.
