Tank Seal Integrity

[karmann]

Hi,
Hopefully someone with experience or knowledge of tanks construction will see this and help me out. My 150 Gallon extra tall has what appears to be separation or voids on the beveled section of on the right side.
I am hesitant to call it air bubbles because there are few of those and I know it is normal to see occasional air bubbles as long as they don't get bigger.

tank has been running for 4 months now, and I have been monitoring the seal for couple of months by taking pictures with very little change, maybe one or two more small dots show up and I have them marked below.

what is your guys thoughts on this? the none beveled section seems to fine.
is that normal, have you seen it before?
Thanks in advance.

Shameless bump before I pull the trigger on a new tank. :/

honestly, if it was just like that at the top of the tank, i wouldn't be quite as concerned as if it were on the bottom...

i'd be more concerned if the tank was racking/unlevel and that's what was causing it.

plus, this doesn't look like a rimless tank. So, if it did leak, i don't think it's gonna like, a pane of glass just flops out and pours everywhere. I think if it were to become problematic it'd develop slowly

by all means, get a new tank if you don't feel comfortable. Admittedly, the silicon on my tanks all look pretty much perfect (aqueon) so I guess i'm not one to talk, but i believe it's marineland that make those 150XH's and it's not the first time i've heard of the silicone going bad on a marineland tank....i purposely avoided them, but this is subjective hearsay at best

Thank you @LXXero makes a lot of sense, I will continue to watch it and if I came across a good deal on a new tank it will happen sooner than later.
