it is and the round corners are not hard to keep clean if you have a small cleaner, i have 2 of them i use for QT and they work great and are inexpensive, i definitely like the red sea better for a display system but the cube is a good second in my opinion and i will go with red sea when i do my office tankIs the coral life acrylic? I see the edges look round - and hard to clean 'in an. office'. But thats just me. If it were me I would get the Red Sea nano - with the stand. it lets you store all the stuff you need for the tank with the tank - its clean looking and not a big footprint.
