Reusing an old tank I have in storage, is it a bad idea?

I have a 24 inch tall hex tank with a build date of 1987 running in my kids room, it sat in a crawlspace under my dads house for the past ~10 years.

Like most said, leak test it and go.
 
Regardless I would rather spend a day or 2 taking a tank apart...to redo seams and then reseal apose to spending 300-500 on a brand new tank....King Of DIY does a new glass tank build and shows you how to to structural seems....really not as hard as people are making it sound....just need a right angle and another person to help hold pieces...i think you guys are confusing labor intensive with difficulty it's really not difficult just labor intensive....

That won't do a thing to fix a leaking tank. The "inside" silicone is cosmetic only!



I've done it correctly a couple times and it IS NOT EASY! You must completely disassemble the tank. All 5 panels must be cleaned of all traces of silicone, and then you have to put it all back together, and the "silicone" you get from HD/Lowes is not the correct type - yuo need silicone adhesive (momentive RTV or similar) not silicone sealant (GE type I)

If it leaks I would just go buy another tank.

I've resealed lots of tanks exactly the way you're saying is wrong. It works just fine and has for years. The silicone between the panels is structural, yes. But the silicone fileted into the corners does most of the sealing. Unless you really want to get ambitious, there's no need to completely tear the panels apart. Even if you do, it's not that hard. Time consuming and a pain in the rear, but not hard.
Either way, as others have said above, if it passes a leak test it's fine.
 
Please feel free to use whatever method works for you. Personally, if I'm going to do it, I'm going to do it right.
