You should at least cycle the rock sperately. An even better idea might be to bleach it or even an acid bath in muriatic acid mixed 1/10 with water. Do a little research on those before taking the plunge, but if done properly they're totally safe.

Thanks for trying to help guys but,
It's important to understand the difference between the different rock we sell and when it was sold. The old Fiji (pre-Feb09) was sold "as collected" and was loaded with organics. After Feb 09 all Fiji and our Key Largo rock has shipped "Pre-Cycled" or "Cooked" after this Pre cycling the Fiji is mostly free from organics and the Key Largo completley free of organics.
For the Key Largo
While clean and "technically ready to tank without issue I always suggest allowing the rock to colonize with bacteria before adding.
You can do this with just a week in a rubbermaid tote and a bottle of Fritz 900. (you can seed with some of your established rock but the fritz will be faster)
This will help to avoid/ minimize a diatom or other nuisance outbreak common when adding any dead mass to a system."
Bottom line is:
It's the cleanest rock you'll find and more than likely you'd be fine, BUT taking the time to be "on the safe side" is always prudent.
For Fiji
Follow same but test, this rock is very clean but still may produce some ammonia.
Thanks

If you are purchasing this rock from LFS or on line wholesaler you will have to cycle the rock for a min. of 10days to 2 wks. Keep check of the water paremeters that the rock is in, might even add some cycling bacteria to the container to seed it and boost the cycling process.
Test the water in the curing container every 2-4 days when nitrites go down and all paremeters are good. Its good to go. Also I would rinse the rock thoroughly in saltwater or RO water prior to putting it into your curing container to get off excess sand,dead matter whatever.
