Now that its there---Am I supposed to "feed it" something?
If there is stuff dying on the rock, and bacteria eating that, isnt there
something I should be adding to the water to feed the stuff thats still
alive in the rock?

I've never seen this mentioned in books, but my take is that the stuff should be
fed. Just dump in a little fish food every day; that will decay and produce the
ammonia, nitrites, etc. needed by the bacteria.
