My frag tank is from CD. It's been running for about a year.
It has some silicone imperfections but that doesn't bother me much. Also a part of one of the edges on a top euro-brace pane is not smooth, like it wasn't finished properly or something went wrong when they beveled it. Not really noticeable.
IIRC they were late about 2 months. They did make a mistake with where I wanted the holes, which they caught themselves after the tank was 'done'. So they had to remove the back pane and silicone the replacement back in. I hope that didn't significantly affect the integrity of the tank in the long run. It seems like it's built like a tank and I would be surprised if it leaks (knocks on wood).
The main gripe with this tank is the double top eurobrace design. It's cool for structural stability, but I don't like how there is black silicone between the two panes. So there is like 3.5 inches around the edge where light can't penetrate. It's just a personal preference and I'm sure most wouldn't mind. But for me, when I consider my lighting with this tank, I am actually basing that on the opening between the eurobraces, and not the actual tank dimensions. Like my tank is 5 feet long, it annoys me that if I get a 5 foot T5 fixture, it's technically "hanging over" the open space, which is only 53". So light will be hitting black eurobrace. So what's the answer, get a 4 foot fixture? But now you aren't lighting all the way across. Maybe this doesn't matter if you are going with "puck-style" lighting, but it sure bothers me. But at the same time, it pretty much rules out putting a skinny frag rack on the side glass. In my case it doesn't matter because it's a frag tank anyway.
***I don't blame them for this though, the bottom line is I did not put enough thought/research on their design.***
Maybe if they could make it with a single eurobrace or put clear silicone on top without sacrificing aesthetics, I would consider them in the future for a display tank. Or maybe I'll get it "bigger" to make up for the black edge on top.
Overall, this tank is serving it's purpose, I'm satisfied, and it seems like a solid tank.
I do have a short YT video on mine when I first filled it up. If you want to see it, PM me and I'll give you the link.
