Closing levels question

[Tinkerpt]

So I SLAM'd the pool yesterday to my SLAM level and maintained it overnight. FC level today is only down to 15. PH 7.6 TA 90. Pool company is coming tomorrow. Is it ok to close with this FC level and if so should I add the polyquat 60 or not. I am in northern virginia and water temp is 58.
Thanks.

Assuming your CYA is 40 or so, you are fine to close at 15 FC.

The Poly 60 is insurance, some use it some don't.
