Sand looks nice but I think after a while when you see all the debris/detritus laying on top of it, it kinda makes your tank look well shibby. Personally my tanks are bare bottom, I have a few plecos and they alone make enough crap to clean up I threw out my sand/gravel. A trick that may work for you is to place a powerhead on one end of the tank. If you get the circulation right you can centralize an area where most of the debris will gather. I don't know how well this method works on tank with substrate but since most things lay on top of the sand it seems like it might work for ya.
