All in all I am pretty satisfied with the winterizing last year. I had a lot of trouble during opening last year, but this year I think I started early enough to (hopefully) keep it under control. The water was clear when the cover came off but went cloudy after the start of shocking. It is a bit better today but I notice I did fall below the shock level of 16 so I am about to get that back up now.
Should I be concerned with any of those numbers, particularly pH and TA?
