Doesn’t look like a failure.. looks more like a crappy weld to begin with.. failing it’s white and cloudy, almost looks like kalk got in the joint is the best I can describe it.

This would be a failing joint as you can see the acrylic has delaminated from each other. Cloudy..

Most likely those bubbles have been there since the day it was built… I can’t see it in person, but if you don’t see any white cloudy joints like I posted above you’re fine.. tank was built with the correct material thickness so that’s a bonus lol..

Thank you for that information there is no cloudiness whatsoever I bought the tank second had 3 years ago had it running in my living room until I moved it 3 months ago to my almost finished basment

Is the bow in the tank normal to have? I noticed it since day one just didn't put a level on it till today

Yeah it will have a slight bow being 30” tall but nothing to worry about.. acrylic absorbs about 3% of water over time and makes it a tad pliable.

I am not surprised, that's a lot of water pushing on those 20 inches.

My old tenecor tank had a massive center bow (almost 2 inches) and all the seams looked exactly like you posted. It is just bad workmanship and they didn’t use enough glue. It should still hold fine.
