I have noticed that the front and back sides of the aquarium are bowing outward. It's a glass 20 tall, 24x12x16 (LxWxH), made by perfecto. I have never noticed this before, but the last time I used it was 5 years ago, so I wouldn't remember. The warping is just under 1/4 inch at the very center of the aquarium.

Is this just normal wear for older aquariums? I know larger aquariums are prone to this stress b/c of the long length, and they have a bar running across the top rim between the front and backsides so not too break. However, this is a relatively small aquarium and I'm sure should not be bending under stress. Wrong?

I think all glass tanks do a little bending new and old.

I thought glass tanks were not supposed to bow. It must be thin glass to do that.


Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

usually it's the large tanks that bow. 1/4" seems like a lot for a 20gallon...but then again glass isn't a true solid at room temperature, which is why it can bow 1/4" without shattering

Just keep an eye on it. All-Glass is usually a pretty reliable brand.

Thanks for all the replies. I guess it seems that most experince a little bending. The glass is standard thinkness, about 1/4 inch.

Malklore, the aquarium isn't an all-glass, its made by perfecto. This is why I brought it too attention, because I know if it was an all-glass, I probably would be overly concerned over nothing. The 1/4 inch sounds a lot worse than it seems; when looking at it, it isn't that terrible.

I guess I'm good for now. But of course, until it breaks is when I know I will need a new aquarium. :shock:

I don't want to be a downer here, but I would not be comfortable with an aquarium that was bowing! :?

Ok, I think I mabey over did it say my aquarium was warping or bowing. It really isn't that bad as it sounds. Its only 1/4 inch, and that really isn't big at all either. Its just slightly bending outward a little bit. 8 years old, so I don't expect it to be perfect.

I bet if you place a perfect straight edge parallel to the top rim the long way, you will discover the glass slightly bending outward. Am I right?
