Fixing cracked glass

[Fsh]

Hi all. Bought a secondhand 550 litre tank. Once I got it in I noticed it had a crack (see pictures). I don’t know if this was from the previous owner or if it happened in transit.
It seems to still hold water. What is my best bet for going about fixing it? Is just silicone enough?
Thanks in advance.

Corner chips are generally just fine, but it looks like some of the glass is missing from the corner?

The only repair is to replace a pane of glass, which isn't worth it. Since the tank is the cheapest part of most any setup, I'd just not worry about the prospects and get a new one.

I agree with the above post. The last thing you want is to have to worry about that chip/crack when everything is all set up and running and filled with livestock

I’ve got my full set up now and out of budget really. It was also a huge upheaval getting the actual tank in and out of my house. I don’t think I can do it again. It really not worth fixing?

This is a video of it if it helps. Don’t know what to do otherwise.

Is that just a chip, or is it a crack that runs along the bottom edge of the back pane? If it's just a small chip, I wouldn't be terribly worried. If it's a crack, that's bad news bears.

550liters (145 gallons) is a lot of water to risk a chipped/cracked bottom corner... especially one that traveling towards the silicone rather than a more traditional scallop. The bottom of the tanks hold the most pressure. If you decide to set it up, just know that there is potential for the seam/glass to fail at that point, dumping the entire tank onto your floor.

I'd consider replacing that entire back panel...

P.S. the video you uploaded is audio only.

Not that it’s not worth it it’s just a TON of work and by doing it yourself you are risking having 550L of water on your floor. So how confident are you in your repair skills?
to repair it, you would need to fully remove all silicone, remove that glass panel, get a new Panel and rebuild the whole tank from scratch with all new silicone everywhere.
so is it worth that effort or worth saving a few more hundred dollars and getting a new one.
Your house, your time, your call.

To risky in my opinion being that close to the silicon. I wouldn’t trust the tank to hold it’s basically a ticking time bomb.

Think you’re all right. I’m not handy with that stuff at all. I’m just do disheartened with it as it was a weeks job just getting it in. I think I’m going to have to pack the hobby in all together. Thanks for the advice guys.

I don’t think it is that serious. But for price of mind I would silicone a strip of glass in the bottom corner to reinforce the joint if your worried about it.

Putting a piece of glass on the outside will add ZERO structural integrity.
