Hello, Dan here. We are currently having our fiberglass pool installed and are hoping to be swimming by this weekend. I have ordered the recommended TF-100, salt test, and magnetic stirrer. Pool is filled and plumbed. We are just waiting on electrician and pool deck. I see a shock packet, so I assume that the contractor will throw that in when the pump starts running. What is typical besides that? Will they get it all balanced and ready for me just to maintain, or is it shock and then turn the keys over to me?
