One other note on management- I only have to add acid about 1x per week during the winter - nothing else. I just unhook 3-4 anchors upstream of the deep end skimmer. I get it mixed in fairly well, even though I’m not dispersing it more evenly around the pool the way it do when the cover isn’t on. My TA never gets too low, regardless of the amount of acid that I add. The downside (or upside depending on your perspective) is that I can’t brush the pool during the winter. That’s one of the reasons I open it up early in the spring - so I can give it a thorough cleaning and let the filter get the debris out of the water.
