if your removing the sand from the tank while moving the tank, its useless, wash it. boil it, then wash it again, it might be safe to use then, there will for sure be a lot of crap in the sand that has died, or grown and died during hte washing process, treat like new sand after the second wash, ie wash again,,, and again until clean
if your leaving it in the tank while moving the tank, it will get disturbed during the moving of the tank and i would place filter floss all over the place to catch the lose crap, cycle for a few weeks as per uncured lr
just my 2.5 cents worth
