Does this type of crack make the tank unusable?
I was given a full reef set-up from a lady who just wanted it out of her house (she was living in her daughters house and conveniently re-modeled....)
I cleaned out the tank today, and noticed this sort of super thin area of glass which must have come off as if it just "lifted" from the underlying glass. It is about 1/2 inch in diameter, and about 1/2 mm thick. I actually found the piece of glass in the sand as I was filtering it out. It appears that 1/2 of the lifted glass area came off under the silicone, the other 1/2 was above it. It is located along the bottom seam, on the right hand side when viewing the front pane. It is a 120 gal all-glass reef ready tank with dual overflows, so it would be a nice one to keep and use. Here are a couple pics to get your oppinions, and whether or not I could just fill in the area with silicone just to be sure. It didn't leak a drop when it was taken down a couple weeks ago. (I didn't take it down myself). Thoughts please? Inside the tank looking at the crack..... Outside the tank looking at the crack... D

Looks like an impact took place right there.. YOu can see a hairline crack starting to split up the top of it as well... I wouldn't risk it..

What if I tried to silicone it, and leak test it in the garage for a couple months?

No! i wouldn't even consider it. Your future investment with a tank like that would be worth the extra 200-300 for a new tank.

I would not use that tank. You can see the hairline crack and with glass its only a matter of time before it spreads.

If you use that tank, you'll have alot to lose. I'd go ahead and get a new tank. For the money and time that goes into this hobby, having the tank break and losing everything is not worth it.

A new tank is a very small investment to make in the long run.. If it cracks and you lose all of your livestock and flood your house it will cost you a whole lot more than 2-300 bucks for a new tank.. IF you are trying to do it on the cheap craiglist is your friend...

I agree with the others. It is not worth it and by the looks of it, it is only a matter of time. Spend the money and get a new one or lose more money later.

I just bought one and its more like $500 for a new 120g RR. That really sucks. Since theres a piece of glass missing from the bottom the new silicone wont hold under all that pressure since silicone is flexable.

That Crack in your picture will spread under load and the tank will fail.. I would either get a new peice of glass at a glass shop and replace it or just buy a new tank.. Like others said the price of the tank compared to all your other equipment and live stock isn't that much. But its one of the most if not the most important things to have right!

$200-300 for a new tank? Its just one busted panel. Id have the local glass shop cut you a new piece of glass and redo that panel... its just glass and silicone.

Shop around for glass price, some are way overpriced. 5-6$/sqr foot for 3/8" is average.

You got it. The best thing for removing the old panels BTW is monowire... the thinnest, strongest metal strand you can get... as the biggest problem with getting out the existing glass is that its such a narrow gap between the panels.
