My 90 Gal is a sun sun, they are out of China, the inbuilt overhead filter i'm still not sold on but as far as tank quality it is really good and pretty think for the size, mine has the curved glass.
Oh these tanks look like my Jebo. Ya, the built in filter suck . Here is a picture of my 116g Jebo tank. This one does not come with a build in filter but does come with 3 power compact tube. I think Sun Sun should be ok. Come to think of it my LFS has a Sun Sun running for over a year now as his display tank. When you buy make sure the store do not store these tanks outside otherwise the silicone may dry up. I heard bad things about Via Aqua tanks being leaking though.
yeh they make small aquariums. i talked to my custom aquarium builder and he told me he has only heard of one plywood tank in aus 0 cement ones and rekons acrylic is extremly high tech. lol. thats how unadvanced we are
