Hey,
I live in south florida, hollywood. i run a low cya 30-40ppm but i test my water all week, usually 4-7 times a week. the water does get tons of sunlight and get very warm during the summer but i only add bleach twice a week. i do add high levels of bleach though when i add. usually i add 2.5gallons/week of 10% bleach. i think whatever works best for you personally is the way to go as long as you are on top of it. i hope that helps somewhat?
