I have a "Crevice" background that is 84" X 31". I have been very pleased with it. Shows no wear or deterioration after 4 years. I also have several of their rocks. The texture is sandy, not smooth, if that makes a difference to you. a little time and algae growth and the look is very realistic. I also have a 72" X 30" background from Aqua Decor that has a smoother texture with a more defined, rocky look. In comparing the two: Universal Rocks has an "end cap" option that finishes the side edges of the background so that there is no gap to allow fish behind it on the ends. Aqua Decor does not have that option, so you can see the raw edge of the background from the sides and fish do get behind the background. Also, Universal Rocks shipped the background in one piece so there are no visible seams. Due to shipping from overseas, Aqua Decor cut the background into three sections that I joined as closely as possible, but the seams are still visible and I hide them with driftwood and plants. The two companies each have a unique look and both are very realistic and tough. I am planning another tank, 130" X 31" and will probably go with Universal Rocks, mostly due to the end cap feature and UR being domestic. They actually invited me to come to their manufacturing plant for a tour when I called to discuss the custom build. Hope this helps.
