My view is that you are disturbing the detritus clinging to the live rock and it is getting scattered around the new tank as you add water. Could be a lot of bacteria mixed in with the stuff but I don't see anything to worry about. If you want to clean it, siphon through a sock into a bucket and return the filtered water to the aquarium.
Next time, swirl the rock in a bucket of water to knock the funk off before you put it into the display tank. Quick swirl in old tank water or fresh tap water, either one will do the trick and put it back in the tank.
It's extra points if you make a basket.
