Help!! Acrylic aquarium crazing.

[Juaniro13]

I need your help. I get conflicting info online, chat gpt and other various sources. I have this 375 gallon acrylic aquarium. It’s 10 feet long, bought used and had it for 6 months. I’m noticing a bit more crazing. Should I be worried? The tank is sitting in an acrylic stand and when I set it up, it was leveled, now it’s tilting very little to one side, both tank and stand. How can this be? My floor in leveled completely. Anyways, I need some opinions on my tank, if anyone can shed some light. This is my first acrylic tank.

Yep, wednesday13 can tell you if you should be worried.

I have zero experience with acrylic tanks, but...if I had a tank that was set up perfectly level on a perfectly level floor...and it started to tilt, even though the floor is still level...I'd be very worried, regardless of what the tank was made of.

And if I also started to see all that weird stuff happening inside of the seams...I'd be scared green.

But, again...no acrylic experience talking here. I'm dying to hear what Russ has to say about this situation.

Like jjohnwm , I have little experience with acrylic, always passed it up in favor of glass. What your photos show doesn't look like what I call "crazing", but more like stress in the welded seams. Again like jjohnwm , that would concern me greatly when coupled with the observation that the tank is no longer level although the floor is unchanged. Hope an acrylic expert can give you a more informed opinion.
