I wouldn't IMO. Think about this. People not only pee in the water, think about all the people who spit, or throw their cigarette buts. dogs who use the bathroom, beer that gets spilled, animals who die and rot on top of it, countless peoples feet that trample over it, the list goes on and on. Then think about taking that filthy media and "cleaning" and by the "" i mean just getting the dust particles out, you cant disinfect sand (id add some bleach if you do). Dumping it in your tank and hoping that nothing weird leaches out and kills your fish. NO THANKS!! But then again the sand could be perfectly fine, I just wouldn't. Just my opinion of course.
