My first tank was/is a Clear for Life Uniquarium, I think about 55g, purchased used!
I actually am embarrassed to admit, I love it so much...
Acrylic, with beautiful beveled front edges, so it's very light. The custom cabinet is very spacious and neatly stores about 80% of my fish schtuff.
The acrylic itself seems like a very nice grade, and for it's mileage doesn't show scratches as much as other acrylics we've seen. The back is a delicious 36 X 5 inches of great compartments... which could hold all kinds of gadgets... but it's been such a clean tank, I never got any. Just layers of Petco filter pads. I keep an edible caulerpa for the veggivores in the display, which probably helps!
Somewhere in it's life, someone built The Sweetest custom canopy for it, with rounded front edges. A dual T5 in the canopy provides enough light for lps and anemones.
I really like the dimensions of the tank, also! It gives the appearance of a much larger tank, because of the canopy and balanced aesthetic. I have often thought the the Clear for Life company makes some "Good looking" tanks! The height allows for coral growth and very fun rock building!
However, because the back compartment width is very generous for an aio, the display area can feel "narrow", and takes some effort to convey a sense of depth in the rock work! The rocks have to be more carefully chosen for character, stability and coral mounting areas. Less is more!
Have had it in constant service for 6+ years and it was probably "very old" when we purchased it. So, I think that speaks for how well and thoughtfully it was made!
The fact that it "doesn't leak" makes it a candidate for areas in which I wouldn't try to take a tank/sump combination
So, my experience has been, a generous AIO opens wide possibilities, where sump driven tanks dare not tread!! Clear for Life made a great tank.
