This is the first year I have left my pool open in winter. We have had below freezing temps at night for over a week. I know the SWG does not produce chlorine below 60. My water temp right now is 47. I leave my pump running 24/7 except when I am dipping leaves. I have the SWG at 00. It won't go off unless I turn off the pump. Should I unplug it there where it plugs into the salt cell or just leave it plugged in? The only benefit I am getting from it is being able to check the water temp. (Which I like!) I have a few leaves in the pool but other than that it is super clear and chlorine stays around 3. All chemicals were in range last week when I checked them.
