I didn't think so, but then thought I remembered reading a thread that said you should feed your liverock, my question was feed it what?...LOL
A suitable number for phosphates? You mean 0?

So you do need to feed the live rock in an empty tank?
The bacteria needs a source of food in the form of the nitrate cycle, so yes in the aquarium Very small amounts of food to "feed" the bacteria.
but you do need lights!
Only if there are critters growing on the rock that require the symbiotic algea in their tissues fed. Otherwise the rock with bacteria only does not require light.
