Thinking a bit ahead but don't won't to be caught off guard this fall. We are 3-4 weeks into getting our new pool up and running. It is a SWG vinyl liner pool. We choose not to have a winter cover installed and want to keep the pool running throughout the year. It has a Omnilogic Pl control unit that has the winter freeze protection.
My question is if i understand right the swg does not operate when the water gets to winter temps. what do people do about keeping the pool sanitized / chlorine through the winter months?
We live in middle Tennessee . Temps get pretty cold in Jan and Feb. We will have a few several sub freezing nights and days.
We also usually have several speeds on 50-65 degree days those same months and for sure the months leading up to and after those .
I want to keep the pool running and have it ready as soon as the spring temps stabilize.
Our pool has ( well will have ) a rico rock 4ft waterfall that we will winterize. But also a tanning ledge with bubblers and a deep end win out that has 4 jets that i want to keep running.

What type of and how do most people sanitize during cold months that leave the pool close to summer start up . i feel we will definitely have algae issues during mild winter months without keep stable chlorine levels . Im totally unknowledgeable of what to use or how to use it.

Any direction would be appreciated. Thanks

And test the same as summer months? Keep all other levels the same?
Liquid chlorine, as in Sodium hypochlorite i assume?
You need to continue to test. During cold water you can test once a week.
Yes, keep everything in the normal ranges.
Liquid chlorine is sodium hypochlorite is bleach.
