    chlorine loss

    is a chlorine loss of 4 ppm over 24 hours normal. my pool is uncovered in atlanta area with lite usage. cya level is 40. i have to add 96 oz. of 6% bleach every night to boost level up to 7 ppm.

    I am also in the Atlanta are (West side) and I average somewhere between 3 and 4 since my install (7/6/09). I am getting sun from around 0830-1800 daily. I am no expert, but there are plenty on this forum that can answer the question I am sure.

    2ppm is the going rate. that's a bit high if you mean from 8am-8am. how about sunlight? pools in sun all day in hot climates can benefit from a bit more cya. what are your other numbers? increased chlorine demand is a first sign of algae, but this loss could be normal for you. how does the water look?

    Re: chlorine loss

    It's hard to say if it's normal. Have you done an overnight chlorine drop test? If you haven't then I'd suggest you do one. Once you do that and ensure you don't have organics helping you out with it, then you might consider bumping your CYA up to 50 and see if that helps. I know it did mine.

    pool has been up 2 months. water looks great. i think if i cover pool as much as possible and increase cya a bit maybe that will help decrease the loss. ph stays around 7.6 ta is steady at 100.

    Re: chlorine loss

    If you're at 40 now, try bringing it up to 50. I read posts from people in the South who run at 60, occasionally higher, so you have some "head room" to play with here.
