As an aside, after adding LC in the evening, let's say, to bump FC from 4 to 8ppm, how long should I wait to roll out the solar cover? If 8 is still squarely within swimming comfort, should I give it 30 minutes? an hour? to marinate before covering? No wait at all? I'm guessing that all of those might be viable, but less wait may degrade cover sooner than consistently waiting after adding chemicals.
Currently, based on my limited knowledge, that seems to be the most inconvenient part. I'd love the cover on overnight right after adding chemicals, to retain heat, and already be there when the sun shows up next day. But I feel compelled at the moment to let the filter run for a while after adding chlorine, which means I might be pushing til 10pm or so, and at that point, I just don't feel like covering it haha. Then the next day it feels counterproductive to cover before work (I work from home now indefinitely, given the pandemic, which is convenient for this), only to open it 4 hrs later when the family wants to swim around noon or 1pm.
