Winter Pump Schedule ??

I'm not planning on putting a cover on my pool, what is the recommended pump schedule for winter? Right now I'm running it 9 hrs. per day and my salt water generator is running 5 hrs. Not much swimming and it's all good.

I'm in North Georgia so it will get fairly cold here.

Aquarite SWG won't produce chlorine if the water temp goes below 50 (unless on superchlorinate). I just happened to read that in my manual last night. Not sure if that will be an issue.
