from what i understand reading this site, it is a good idea to bump up my fc a couple right before people are going to be swimming if there are a good number of them or if there are a few kids. prevention instead of fixing, right?
so my question is, i get a phone call that 8 people including kids are coming to swim in like 10 mins, can i drop in my 36 oz. of 10% before they jump in?
how much can i pour in? (maybe i am 3 below target and want 2 above, so i need like 90 oz.)
any good rules of thumb?
thanks again for all the clean water and help
