Someone is selling this on craigslist:

Was that stuff once alive? Also can it be seeded like LR? Im guessing no on this one. But I had to ask.

yea used to be LPS and SPS corals. can hold bacteria and become live but isnt as near beneficial as lr and will not stay white.

I would smash them up and use them in a calcium reactor.
