i have 15ish lbs of dried out rock. i got it from a guy who had both fresh water and saltwater but had these rocks in both tanks. (some in one and some in the other) most of the rock is kinda greenish and i was wondering if it was okay to use or if a vinegar bath would clean it up. or is it just not worth dealing with?

u can scrub it with some tap water and a brush then put it in a bucket of saltwater with a power head and heater to re-cycle it.

If it is calcium based rock, the vinegar will dissolve it. I tested sand to see if it was argonite by putting it in vinegar to dissolve it. Depending on your tank size I would put a little into your tank every two weeks until you have it all in.
