New tank acrylic crazing?

[mdk16]

I just got the lights on my new 120 acrylic tank from a reputable manufacturer and noticed that along both edges where the sides meet the back wall I have 1/16" to 1/8" parallel cracks most likely crazing from what I've read. These marks are every 1/4" or so from the bottom of the tank to the middle third.
Should I make an issue of this crazing with the manufacturer? I have only used the Novus cleaning products on the tank. Its brand new, unfortunately I'm mid way through my cycle, no fish yet.
Is this crazing likely to get worse or even worse fail. 120 gallons on my living room floor would probably put me in divorce court.
thank you.

Are you sure its crazing. Crazing is when there are small cracks that are not in a line. they are like a shatter effect. Now if you use any cleaner such as windex or any ammonia cleaner for that matter, it will cause crazing and that would not be covered under warranty. The reason this happens is because acrylic is porous and the ammonia dries out the acrylic. Crazing also happens when the acrylic is under too much pressure/stress. If there is separation at the seems then that is covered from the warranty because acrylic is molecularly bonded and if it were sealed correctly, there would be no separation. Either way, I would contact the manufacturer and let them know of your situation before it one day splits open.

I tried to take pictures to post but due to the glare and reflection they did not show the lines. These lines are all in line with each other at a 90degree to the back wall. From what I read about crazing, if the material is stressed you can see these lines.
It is a very well made tank, 5/8" thick. I contacted the manufacturer by email last night and have not yet recieved a reply. I'll keep you posted.

I have an acrylic tank myself. - I have no cracks or anything that sounds ANYTHING like your mentioning. - It looks like one seamless piece of acrylic, with the exception of the back/bottom where they meet. - There is only a small thin line, and you can barely see it.
I'd say call the manufacture.
