How urgent is this 125G drip leak?

After the first month, I may just perform a monthly measure of the leak to make sure things seem stable enough. Even if I do end up finding a job where I stay in the current house, the end goal was to build a 12ft x 3.5ft x 2 or 3ft fiberglass tank to replace this one, and use this as a quarantine tank until we have all the initial fish we want. That wouldn't be finished for at least another 2 years though as I have other projects that take priority.

You may already be aware, but something I would be concerned with is that Aqueon 125’s are built with tempered glass, on the bottom. The leak won’t be from the brace, so somewhere it sounds like the silicone has failed. Tempered glass can be a bit unpredictable with twists, shifts in stress, etc, and is only used by the large manufacturers for liability purposes - as in nobody loses a hand or arm when/if a bottom blows out. But if the bottom was to blow, it will be a catastrophic failure and having a sump below will only be of help with catching some of the glass. At the end of the day the ri$k factor can only be determined by you. In my home, I would have already drained the tank. Good luck.

Well I have a good update. The leak has slowed so much I can't even catch a drop falling to know where to put the cup to measure it.

That is true. Hopefully if it's no longer leaking, the glass doesn't have any new stress on it and it holds.

so, that has to be water coming from somewhere else and running down to that point to drip out of. There is no where at that point to leak out of unless there was an actual hole in the bottom panel at that point, which would be very unlikely. on my Aqueon 150g, made in 2008, the braces aren't siliconed on to the bottom of the tank, they are free floating. Yours is likely the same?

Happy to hear that!
No need to get paranoid—at worst, it’s bad, but not so bad as your child getting a broken leg (or heart).
Notwithstanding that funny Robert Downey Jr meme!

Yup, during the leak I could actually tell there was a gap with the water running between it and the glass. I think the water is coming from the back wall glass, but all of it was dry on the outside, even a bit dusty in a consistent way that it didn't seem like any water had disturbed it. Pretty sure it's a weakness in the bottom silicone and not the top.

Keep in mind, the act of moving it (if you relocate) will wiggle the silicon and potentially reopen and widen any disruption in the seal. Expect it to come back and maybe come back worse after the move. I'm not saying it will fail... just saying have raised awareness and a plan B.
