Good evening. I found a pretty big dead rat in our skimmer. Do I need to shock the pool to SLAM level or a decent overchlorination would suffice? (my SLAM level is 24… I already brought FC up to 16ppm and stopped, wondering if I really need to bring it up to 24; it’s last week of vacation and probably summer in MA and letting my kid swim in FC higher than 10 makes me nervous - hence the question… but I don’t want to take any health risks either; my cya right now is 60). Thank you.
