How Long Does A Glass Tank Last

[Live_Rock'r]

I looked at some manufacturers web sites and after quite a few years in the hobby I am still not sure of the shelf life of a tank. Should they be replaced after 5 or 10 years? How long do silicone seals hold? I have a standard 75 AGA that I have had for going on 6 years. Is it time to upgrade to a 90 Oceanic to prevent a leak or major catastrophe in my home??? Or can I expect my tank to last another 6 years?

I hope tanks last for more than 5 or 6 years or Im in trouble.

Glass tanks last forever I converted my 30 year old glass 60 gallon into the sump for my 135 gallon this past June

Well, I know in my parent's house their windows are so old, they are starting to warp. When you look through the glass, you can see how it's starting to ripple. So I would assume this could be an issue for an aquarium, but thats probably for your kids, or grand kids to worry about. :lol: Other than that... if it sits dry for any period of time I usually re-caulk the tank since it's easy enough. Otherwise the caulk seems to dry and out become flakey, and I don't trust it to hold.

So IMO, as long as there is water in the tank, I wouldn't worry about it. If it sat dry for more than a 6 months to a year, I like to re-caulk it.
