Did I Buy Uncured Rock?

Cured rock, ime, is rock that leaves no ammonia or nitrite in the water. That would indicate all the dead stuff has already been processed by bacteria that has colonized the rock during the curing process. In this case, the rock was in the lfs's tank for a month or so.

However, perhaps it is possible that there's enough bacteria on the rock to be processing the little bit of dead stuff still on the rock.

Good point, and one worth considering.

BTW, last night before going to bed, I again tested the water in the bucket where the new rock is, and ammonia and nitrite are both 0 ppm.
