i have some pieces of old live rock that has been stored in the closet for some years now. i was just wonderin if i cleaned it off first and put it back into my system, would it cause any problems. just wondering if maybe there could be some stuff that i can't see that would cause a spike in ammonia or something. nothing's on the rock, just a little salt creep. would like to bring this rock back from the dead. any info would be appreciated.
