Should i rebuild this tank?

[Raw84]

Hi everyone,

I recently bought a 50G tank off my cousin, she's had it for a few years and she bought it from Facebook marketplace. I spotted a couple of areas that didn't look right, however, since I'm still rather new I wanted you opinion on if I should take it apart and silicone it back together or if it will be fine? We have 2 pet shops where I live but no aquarium shop so there nobody I can go to for advice where I live. I've attached 2 pics of the area, the rest of the tank looks fine so I'm not sure if that's how it was made or an issue. Any advice would be great. Cheers

It's going to be hard to get clear answers from a photo. It looks okay to me, but I have my tanks in a garage and can take more risks.

What are the tank dimensions (length x width x height)?
How thick is the glass?

On the second picture, are the bubbles in the silicon in the middle of the sheet of glass or on the edge of the glass?

---------------------

The first picture doesn't look like an issue. Someone has just added a bit of clear silicon to the outside to fill the gap.

The second picture has a lot of small bubbles in the silicon. If they have been there for years I would say it's fine and just monitor them. If they start to get bigger then take the pane of glass off and redo it.

Can you ask your cousin if it had the bubbles when she got it?

It's hard to tell for sure, but if in doubt go ahead and reseal it. There are tons of good youtube vids on how to do it, and it really isn't all that complicated. You don't have to take the tank apart; you simply remove the external glue and reseal the seams. The hardest part is scraping and cleaning off all the old silicone so the new stuff has a good surface to adhere to. I've done a few, and if I can do it, chances are you can too. If you have specific questions on how to do it I'd be happy to help, and I know many others on the forum are also familiar with the process.
