putting live rock into an est. tank

I need to add several pounds of live rock to my 110g. I've been in the process of upgrading the entire tank (lighting, sump/fuge, etc.) and need to replace the majority, if not all, of this texas 'holey' rock I've got. How much or can i even put non-cured live rock in the main display w/out crashing it? LFS told me not more than 10lbs at a time...forgot to ask him what kind of time frame we were talking about. What do ya'll think of this idea??

ps. tank's coming up on 5 years old.

 

10 pounds a week or more...whatever you are comfortable with....
I would do a week and a half to 2 weeks....but it is a rather large tank so maybe not that long....
