Help: Putting new rock structure into existing reef tank

[Olympius]

I built a large new rock structure to add into my tank. Is it ok to just rinse with RO and put it straight into the system or should I let soak? There are two additional large structures already in the tank.

Is it alternatively safe to spray it down with hose water and let dry for a couple of days?

I'd just rinse it with a hose, let the water drain off, and put it in.
