    Ok about 18 years ago I purchased what I believe was called cat paw coral (dead). This was used for decorative pieces in my first FOWLR setup. They've been dry 4 years 6 months ago I placed them in a friends saltwater setup. three days ago I transfered my 54 corners' contents to a 5' 120 gallon when if ever can I consider these pieces to be live rock? I added these pieces to the 120.

    It is a dry heat, yeah right !
    Live refers to the presence of denitrifying bacteria upon and within a medium. Colonization of said medium is dependent on other variables, temp, SG....presence of bacteria on other media. These denitrifying bacteria take roughly 4-8 weeks to colonize to the extent that they adequately complete the nitrogen cycle.
