What should FC be when closing pool?

[SirSwimAlot]

In the guide, it says to slam the pool, then let it come down to normal levels.

I also read other people saying they close the pool at slam levels.

I bring the FC up to shock level for my CYA the day/night before closing. Then I close the next day. It's not overly critical what FC you close at as long as it's elevated above target levels. It's more critical that your water is cold. 60 degrees.
