That is not petrified wood at all. It's a limestone of some sort, reaction to HCL and the weathering gives it away. It will alter your water parameters, but should be safe for your inhabitants. Keep in mind if you bleach it, it will turn bone white. That may or may not be your goal, but keep in mind when preparing it for your aquarium.
