Welcome to TFP! First let's confirm some things:
1 - How are you testing your water?
2 - Do you plan to fully close your pool? Disconnect parts, plumbing, blow-out lines, etc? Or just minimal operations like many of us in the warmer climates?
3 - Tell us more about your pool by updating your signature. All that info helps to answer questions. See my signature as an example.
With t hat info we can be sure to give you some solid advice. Also be sure to bookmark our Pool Care Basics page.
