If you where really worried about it you could bleach the old rock to dissolve the organics then cure it/ re seed it , but maybe that's just me an im too cheap to throw something away that cost me 4$ a lb .

I agree, most of us don't throw it away. And my rock is the old crud from the LFS here it costs more than $4lb.
The rock from the ocean is old but it is treated by Mother Nature and doesn't exist in a glass box in artificial salt water.
IMO
