Well..............I've had a wonderful 1st year with my new pool in part to my SWG but more due to the helpful advice I recieved here. My pool was nothing but sparkling clear all year and I've really got a grasp on water chemistry. I am not closing my pool but we are already having lows around freezing. Water temp is 55 and I really don't see it getting any higher. Should I remove the cell from my AutoPilot for the winter and just use bleach as needed? It seems like the thing to do but would appreciate any advice (Sean?).
