Work at an outdoor private day camp pool, 70,000 gal, gunite, bromine sanitizer, sand filters. We have 70 kids a day for lessons/camp and weekend pool birthday parties. Not enough time in between for full weekly shocking. Is it okay to add a bag of shock daily instead of all at once??? The pool is always balanced, have a through test kit. We didn't have birthday parties last year on the weekends so it wasn't a problem till now. Any advice??
