syphon with live sand?

I have only done water change since changing my substrate over to live sand last week. I did it by just scooping water out. I have a syphon hose like this left over from my freshwater setup.

Is it recommended to use this with live sand? I'm concerned that I would suck the good microbacteria out of the sand. Of course I would never use it to fill the tank with tap water.

Sorry if this is a dumb question. Thanks.

I was just about to ask the same thing. When cleaning a reef tank do we move the sand or not? I have a few guys that clean up the sand but is that enough?
