I am looking to upgrade my tank. I have always kept glass systems, but, a member of my local reef club is getting out of the hobby for the while and is selling his large, 350 gallon acrylic tank. There are almost no scratches on the thing that I could see when I went to look at it. But, what I did notice was crazing in the tank's perimeter bracing (or eurobracing, whatever you want to call it). That was the only place I saw it, but, it was consistent across the entire top. He runs LEDs over it, and, for a brief while, it was lit by t5s. Halides were never used over it. The tank is about 3-4 years old, and is made of 3/4" thick acrylic on all sides, including the top perimeter base. Tank manufacturer is Tenecor.
The craze lines look to be internal, versus at the very surface. They are all vertical, and can be seen when you look through the cut end of the acrylic brace (the top sits on top of the acrylic walls of the tank, versus being recessed in between them, so you can easily see the craze lines). I don't see any of them running across the top the brace (the horizontal, flat surface).
So, my question for acrylic experts is: "Is this a tank I should not consider?"
Thanks for any and all input.
