Take a look about the Red Sea, I have worked with them in person and they are great setups for what you pay. Also to my knowledge the back isnt painted black but rather is smoke colored glass (just really dark clear glass, made it easier for them to make baffles that will not have as great of potential to slip if it was acrylic.) The pluses to it for you in my opinion are this: One all inclusive built into the back means moving is a whole lot easier than taking apart and resetting up a sump style filtration system. Two The potential for a flooding tank (I am assuming that you rent wherever you move) is less because its not draining into a sump. Three plug and play capability, you litrally dont have to think about what equipment to get for the tank itself because it already comes with your skimmer, heater, pumps, 6 HO T5, mech/biological filtration. Everything is included, and yet should something get broken or lost (in a move) it would be easy enough to replace. Overall its a great tank for someone who doesnt want to worry about little things that the rest of us have to. HOWEVER that being said I personally after owning a Biocube 29 wouldnt ever buy another all-in-one tank ever again. The reason for this is stupid but its because I personally love picking out and researching all the different compontents that go into a tank. and i love to built my own fitration system be it sumps or in an all-in-one style like the tank I am currently running. But if you dont get a red sea I personally would go with a Reef Ready tank of 18 inches in width. Those overflow boxes take up a lot of room to begin with and plus 18 just makes it look better/more natural.
