Split from cya-t51106.html Butterfly
I have the same problem -- today while super sunny it seems I'm down to about 25. However, I dosed to 45 at the beginning of the season (first year in this house/pool) so I'm unclear whether it's possible to loose 20 ppm to splash out/rain/refill dilution. My reasoning is that since I'd added borates at the same time, both readings should be about the same, and borate test "seems" closer to the original 50 (color strips, gah!)
So, I realize every pool is different, but on average, how much cya would be "normal" to loose to splash out after 2 months with daily use? Will test again today. Daily Chlorine use is slightly higher than it was previously, eg 2.5 - 3 ppm per day versus 2 ppm previously (my pool always has a bit of shade in various spots so I'm never direct sun all day, in case you're thinking 2 ppm sounds low.)
