To cycle or not to cycle....?

Hey guys,

I just recently had a tank made. A custom 2.5g. My question is this:

If I take 2.5 gallons out of my existing tank, only used cured live rock, but purchase 3 lbs of live sand, will the "new" live sand cause a cycle? Or will the existing water, and cured rock negate a cycle?

Thanks in advance!
