Okay, I've read the Closing an Inground Pool thread several times and don't understand something. I plan on raising the FC to shock level about 1 week prior to closing and keeping it there for 3 days. After that, I will let it drift back down. The day before closing, I will add polyquat 60 and let circulate for 24 hours. My question is on the day of closing should I test the FC level and bring it back up to shock or somewhere in the middle? I have read that the Polyquat 60 uses up a good deal of the FC and am wondering what my actual FC level should be when closing.
