Ok, here in West Virginia the nights are getting colder and mountaineers are on their way to a National Championship ( i just jinxed them). anyways.....
I was going to close my pool next weekend. I usually wait till Oct 1 but will be away then.
My water temp was 70 today, no one is swimming

Current FC 14 and have not added bleach since Thursday. Ph and everything is in balance and within spec. Cya is about 70 as I run this all yr long

I read you should shock the pool and then add one bottle of polyquat. i was going to add poly Monday and recirc for 48 hrs then add more bleach to get to shock level after the poly eats what FC it wants. Then hopefully close this weekend.
Any other ideas or should I wait to water temp to go down some more.

Thanks
Mike
