Dead rubble rock question

I got 10-20 Lbs of rubbe rock from a fellow reefer the other day for free but here is the deal.
Back in early december 2008 he had a tank disaster and ended up taking out lots of LR and rubble from his system. So the rock he gave me was once live rock but has been exposed to air for 8 months now. All the rocks are dry and light.
My question is what do I have to do to safely introduce these rocks into my system?

 

well i just dumped all of the dry live rock pieces into my fuge at once and watched for ammonia.
but if you wanted to be on the safer side put a few pices in every day

 

Thats what i was thinkin just do a little at a time.

 

Did he pull them out due to algae takeover or something? If he did you will want to nuke the rock first or introduce algae spores into your system.

 

It was from a huge power outage that was all over new england area.

 

lots of NH and Mass where with out power for over a week.

 

well if you know his tank was algae free go ahead and toss it in.

 

the have been out long enough anything that was on them is now dead. toss em in
