How long will a glass aquarium last?

Does anyone have any feedback on Marineland 180 gallon tanks, I have been looking at some used ones and was curious how their silicone holds up?

Fyi marineland is owned by perfecto and perfecto makes some of the best tanks out there.

I have been debating this, I have a 265g that is about 15 years old. There are small leaks in the overflows that I have noticed during the bigger water changes. I have seen this before on a 210g after ~8-10 years.

As someone else mentioned, I too think moving the larger tanks likely creates unusual stress that may shorten hurt the integrity of the seals.

I have a dry to slight moist salt creep underneath my 265. I first noticed it several months ago, priced a replacement & built a new stand. The creep does not seem to be getting any worse, I check it regularly and keep a couple water alarms underneath just in case.

I will likely spring for a new one in the very near future. I completely dread the time/inevitable loss/SPS breaks that come with moving everything but it will allow for an upgrade to sump, skimmer, return pumps which I could use.

My 125 is about 18 years old. When I installed it I added the wooden oak corner strips with lots of silicon underneath so at least I have no fear the sides will leak if I damage the inside silicone cleaning the glass over time. Plus if my kids hit the corner with something it is protected. I am assuming the bottom is pretty solid with the plastic frame and silicon oozing out the bottom. They don't make them like that today looking at my more recent breeder tanks.

The trim today is all black but i think its the same material.. problem today is tanks are made to be cheap... thinner glass.. so they all have braces that eventually do crack over time.. and they are cheap on the silicone thickness... thats what really bothers me... braces i csn deal with... its how thin the inner seals are that bugs me...
