Hi again,

Missed a couple of your questions. In North Texas this summer, we've been above 100 degrees for over 50 days and have just now come down into the 80s.

Bleach added in the evening lets the chlorine go to work without being broken down by UV rays.

Instead of adding chemicals on a regular schedule, I test on a regular schedule (initially I tested 2x/day, now once a day) and add whatever is necessary, whenever it's necessary. I'd test even more if I were trying to kill off algae.
