Help My silicone is dying

[ChiTownRomeo]

Was doing a water change on this aqueon 55 gallon I have had up and running 9 years. Never moved it from the spot it's in. It's on a full stand and leveled since day 1. Today after the 20% water change, I noticed real small air bubbles in the right seam. From the top to the middle are these small bubbles. My paranoid mind has me nervous lol. The inside silicone has been chewed a little. You think its going to leak. Im kinda scared considering im on the 3rd floor apartment.

Hello, it's just old. Aquariums usually need to be resealed every 10yrs. I've done it a few times & it's easy.
You need to move fish & all contents to another tank or a storage tote because it takes a couple of days(48hrs some say 24) for caulking to cure properly.
Scrape all caulking in corners & bottom on inside of tank but do not pull glass panels apart. Remove everything & clean w/acetone. Painter's Tape inside to be caulked & caulk whole tank at once.
I then dip finger in water & smooth out all caulked lines. Remove painters tape & let cure. The cleaning & caulking take a couple of hrs. The picture is a YouTube vid on how it's done. Hopefully this helps you!!!!!

Hmmm I wonder could this be causing it. A few weeks ago my floor and stand got wet. Maybe it became uneven and causing too much pressure on the front glass..... Time to shim
