I would like to add some more of the dry marco rocks

I'm thinking of adding more rock to my tank. When I started I used marcorocks dry base rock, and some LR from my LFS. I would like to add some more of the dry marco rocks, do I need to go through any kind of a process before putting it in the tank?

the only thing i could think of is to soak it and make sure its not leaching anything into the water, but me personally would just rinse in SW and add

Me too. But I have been known to put new rock in a bucket of old water with a powerhead and an air pump to clean it out a bit.

That rock has a long history of contained dried organics that when re-hydrated will cause an ammonia spike. The now sell pre-cured rock meaning they keep it under a shower spray for a while before packing it. I would still put the rock in a container outside the tank for a week with salt water, a heater and a powerhead, and check the levels at the end of the week.

Is the rock ok if it is limestone based?

You mean florida rock? Not good. High phosphate content.
