It will still take some time to cycle. And yes you are killing the bacteria that are in the sand to shorten the cycle. You could use fully cured live rock if you don't want a long cycle. The sand will team with life again once you put it back into the tank, no worries there. The sand is alot finer than crushed coral and bodes better for sand sifting critters.
