help newbie with SWG in winter

[szcakes]

hi, I bought a home this past summer with Autoclear Plus (polaris) SWG, in -ground vinyl liner. After much dismay all winter as to why I was not producing chlorine ( no help from pool store guy), I called the Polaris tech line and they told me it will shut down at about 55 degrees. ok I get that. So what do I do now to keep chlorine up? Can I use those puck chlorine things you put in the skimmer every few days? or is that a no no? I have never used the bleach thing I read about in here cuz the SWG took are of all my chlorine needs this summer. What chlorine level do I want to keep it at for the winter? I have shocked it a few times per pool guy advice but I get zero chlorine result after a few days ( of course). Please give me specific intrsuctions as to how I should address this chlorine issue; I am new and a little dense LOL)

PS: I just cleaned the cell, so that is not the problem I hope.

PSS> I want to add that my stabilizer level is reading low, but the pool guy said don't worry about it until swimming season, is he correct???

Thank you in advance for your help.
