yah so long as you keep everything that might have life on it wet, I think you're good to go. With nor corals or fish I don't even think saving the old water is all that important to be honest, the only reason to re-use it would be to save on salt. So long as the new water is salinity matched, it's not going to harm the bacteria on your rocks and in your sand one bit to do a 100% water change.
