Just wondering if it is ok to close your pool at the SLAM level? Meaning actually putting the cover on over the pool while the chlorine level is at shock level based on corresponding CYA and the slam chart.
Not sure if the chlorine at that level is ok long term over the NJ winter. Since my CYA is around 60 to 80 (will of course retest right before) my chlorine level is accordingly fairly high as well.
Ok? Not ok? Or recommended?
Trying my to avoid opening the pool green like last year. This site has helped me leverage liquid bleach at 5 to 7ppm all summer and no need to shock all summer long.
