sure go ahead
the rock is painted with bac.
it needs only hydration and time to fully activate. you'll be creating a skip cycle aquarium as linked here:

when you fill holding container w sw for a couple weeks, and then move the rocks over to DT they're then ready with bac and the new tank doesn't have to recycle as we label group B rock above. it will be ready. the rocks do not have to be spot fed, they required only saltwater to be added and about 12 days. What is not required is adding ammonia, feed, or any extra bac. water + 12 days.
