HELP! Acrylic 75g tank is bowing a lot! Time to replace??

[SpunCoral]

I've had this tank for several years, and friends of mine owned it for several years before that. I recently moved into a new house where I am viewing the tank from the side more and I'm now noticing just how bad the bowing is.
The tank touches the stand in the middle, and there is almost a half inch gap as the tank reaches the corner, pictured below.
I know acrylic is supposed to bow but im concerned this is excessive. Id rather get ahead of the problem but man I did not want to replace this tank this soon. I'd rather avoid disaster but I want to see what the community thinks. Am I in a rush to replace this system??
Not to mention that the back seams have micro bubbles, I think. My untrained eye can tell if that is bad seem damage or not.

I know little about acrylic but I wouldn’t trust it.

IMO, Time to replace......

I would not be able to sleep with seams looking like that. I would replace ASAP.

That bad?

Those seams look like bad glue joints to begin with.. good part is that looks to be inside the overflow? If so, no pressure in there and you’re prolly okay.. a failing seam in acrylic looks cloudy and white as it separates. That Bowing is a little crazy! But I’m sure it’s done that since the tank was 2 weeks old or so.. do you see minute cracks in the joints? “Crazing” that’s stress related.. I don’t see it being emergency but I’d look into a better tank before you get to far along and can’t sleep at night lol..

That bad?

Yes. 75g of saltwater on your floor is going to cost way more in damage repair and cleanup than replacing the tank. Because if it let's go of course it's going to do so at the worst possible time.

I would look into getting a new tank soon, a tank bowing like that can lead to a disaster over time. Sorry about this happening to you!

Is the bottom of the tank entirely supported by the stand? If not that can add stress to the tank. Acrylic should always be supported entirely by the stand. It might be that the tank is on the thin side as far as the thickness of the acrylic. That would make the tank bulge like it shows in the pictures. I would be looking for a replacement but not many acrylic tanks burst a seam as compared to glass.

Are you sure that's not a CRT TV?? Holy crap I would replace that ASAP.

Mine did the same exact thing. I went ahead and replaced it for a peace of mind . My buddy’s tank was 3 times worse and he kept it half hanging off the stand lol. Acrylic is durable so you have time, but I would definitely get a new tank.

That is a lot of bowing. Those seams are a bit sketchy too. I don't know that I could sleep at night. I replaced my 150gal acrylic when the the seams weren't halve as bad.

I'd be **** scared !!!

Dang, yes thats a "right now" problem. That is 100% going to burst and it'll probably happen when your asleep. Step 1 take the day off of work. Step 2 get a big rubbermaid bin and put everything in it.

I’ve seen worse.
