I actually recommend water changes throughout the cycle, as well. It helps to maintain as much life as possible on the live rock. Not a necessity, nor is it counterproductive as as some may think, but it definitely helps.
Okay. I called my LFS and also asked if they could explain it to me as well and I think I have it down. As far as I know, its just going to be rock, but if my paychecks all of the sudden get fatter(holidays) I'll rethink it.
