It looks like one of my acrylic tanks is failing at the seems. All 4 corners just above the water line. And a crack even at the top just off the seam. All 3 that size i have are bowing. But this one is the worst. The tank is an advanced acrylic 6x2x1 3/4 inch thick rimless. This one was setup first. Maybe 3 years old. How long do I have until total failure? Or a leak? I’m new to acrylic tanks. But I expected to get a lot of years out of these. Is this just poor workmanship? I’m going to contact them. I’ve bought 6 big tanks from them. I’m hoping they take care of me. But if this is the norm I don’t want another one. I’ll go glass. Thanks for any insight.
