how much chlorine do you lose / day ?
did you ever keep a lower level of CYA and find that you lost more chlorine ?

When my CYA is 60 or below, I lose an average of 5 ppm per day, requiring daily chlorine additions. When my CYA is 80-90, which is where I purposely keep it, I only lose about 2 ppm per day, so by staying at the upper end of the best guess chart, I only have to add bleach a couple of times a week, unless I have a really big swimmer load.
