I'm new to using Pool Math after struggling to keep my hottub balanced on my own. I was using a bromine kit from the supplier before. Now, off of the recommendation of a friend, I'm starting over using chlorine bleach. I'm wondering if I need to put in an initial larger amount of chlorine to shock it before resuming normal additions. When I put into the app that I have a reading of zero for chlorine, it tells me to add 2 oz and 2 tsp. When I test the water again though, I get no chlorine reading still. How can I boost those numbers? How often should I be testing the water? How regularly should I plan to be adding bleach? Any info would be so helpful!
