Raka, that's too sad . . .I just had all the same issues on my 110 Clear for Life Tank.... I couldnt believe how thin the acrylic was. The bow was so unsightly and unnerving I never even put fish or hardscape in it. Even after reaching out for reassurance its was still a worry some tank for inside use.
One test fill from me and it was on to the next buyer. Large garage grow out tank which he had 2 of already.
I was given the impression that all their standard tanks are just fine, and I'm the culprit who ordered something bad.
