Chip in new aquarium I JUST bought at petsmart.

I didn't notice it at first but I feel dumb for not looking!!! :( But here is the pictures of the small chip, I am wondering if it is bad or if it is no big deal. =/

Btw, in case anyone remembers me, I'm consolidating most of my fish tanks into a 50 gallon aquarium. Having so many is just too much work.

=/ Sigh. This sucks.

It shouldn't matter at all, as long as it is just a shallow chip. It looks like it is, so I really wouldn't worry.

Thanks Erin. It is just a shallow chip, my parents are not concerned about it, but I just don't want to ruin their home. =/

in a 50g tank, i think any chip is dangerous because of the pressure of all the water in the tank. Even if the initial fill doesn't do any damage, pressure against the glass could cause it to crack more easily in the long run. I would exchange it for a new one.

Did you look at where the chip is? There is no chance of that chip spreading from the weight of the water.


If you can exchange it I would, you paid for a tank with no chips. I am going to guess they wont just exchange it though, because its Petsmart.

Whatever you do, you better hurry - the cat on the bed is anxiously awaiting FISH :)

Even though it's a pain, I think I would take it back.

I'm torn on this one. I think it depends on how much I shelled out for it and also if it's noticable.

But the cat does not seem to mind :)

Well, it's not noticeable because it's in the back. It was 125$ w/ tax. I couldn't care less if the corner in the back is chipped aesthetics-wise... I just want to know if I'm at risk for it blowing up!! And the reason you are torn is because it looks bad, or is it because it is at risk of cracking and causing a LOT of damage. It's on the second floor...

It's sad because it is the only one they had, and it's not like we can prove it was already chipped. =/ I can check the other petsmart, but, what are your thoughts on petsmart and returning a tank that's been half filled with water already?

Edit: Well, I just talked to my dad, and since I kind of need him to help me move all this stuff around, and since my mom is paranoid I'll hit the walls or chip the staircase or w/e, I can't do it by myself. That said, my dad feels that since it's on the corner it does nothing to provide structure to the aquarium, which I agree is true when you think about it (but not everything is as it seems... it could have weakened the area so it might crack under the pressure, etc?). I feel it would be easier to get a new one than to clean up 50 gallons of water, but, I guess it's not up to me. And I don't want to push it too hard, unless you all think it is a risk. I hope you guys notice it is in the corner too and it doesn't seem to mess up any of the silicone attachment. I'm not sure that tiny piece of glass provides any structure since it's on the outside and water does not hit it. But still let me know what you think please!!

Also do fish tanks "leak" or do they "explode"?? I'm under the impression they explode. My parents seem to think "well, if it leaks we'll buy a new one" and im trying to convince them fish tanks don't leak they explode.

How the glass breaks is dependent on the glass, some just crack and hold its shape, others "explode." It depends on the force applied to the glass and type of glass.

As for the location of the chip, I dont understand why it wouldnt crack under pressure. Glass is not like acrylic where the corners are stronger than the open spaces. Glass is way more brittle. Inconsistent strength anywhere on the sheet of glass is a point of weakness. The silicone bonds add some strength to the corners, but if the glass were cracking under pressure, it would spread out towards the center of the tank.

@lorax: Could you explain more about why theres "no chance of the chip spreading"? I'm not a glass expert, but i have worked with glass and acrylic. In my experience, when pressure on glass is not evenly or gradually applied, ie a single point of excess pressure or weakness, the glass is more prone to cracking at that point <-- this is why aquascapers who use big rocks for their tanks put foam below their tank to even out and ease pressure at any one point. Its the same situation with car windshields, when theres a chip, cracks are much more likely to occur from the chipped spot.

There are other factors as well in terms of if the chip will affect the integrity of the tank, if the crack is near the top of the tank, theres less pressure on it. If its near the bottom of the tank, theres more pressure on it. Depth of the chip is also a big factor, a very shallow chip may stand up better to pressure, but if the chip is deep, ie half the thickness of the glass overall, then it may be cause for concern.

The best solution is to call petsmart and tell them about your situation and ask if they will exchange it.

When you say half filled, do you mean filled with gravel, decor, etc or just a test fill where its just water (always test fill tanks for leaks and cracks). If theres been no decor, draining it and wiping it down should be just fine, but with substrate or sumthing, you may have scratched the tank so it would be less likely for petsmart to accept a return.
