No stupid question at all. I believe you treat ocean rock just like completely uncured rock. Put them in a tub with SW
of course with no lights and do weekly if not every 3-4 days water changes, siphon out dead stuff, with a new toothbrush scrub dead stuff off the rock (dead stuff will usually look white or black), this whole proces could take up to 8-12 weeks depending how bad it is. Oh and be aware, it smells baaaaad when rock is curing. It is a lot of work.
Most important thing, make sure it's legal in your area, I know there are some laws against people picking up live rock straight from the ocean.
Hope this helps, lets see what the others have to say.
