Breaking in new plaster

Hello everyone.

This is my first posting to the forum. Thanks for having me.

My wife and I are getting our pool replastered this week. It is getting a 50/50 quartz/sand mixture for its new finish. We have only been in this house for a year and don't know much about the history of the pool. We did very limited testing on our own last seasons new owners, so I am still a novice. That being said, I'm excited to learn more about caring for my own pool.

Does anybody have any advice or special considerations for balancing the new water once the job is done and the pool is refilled?
