Chlorine going up

[cood60]

Wondering what is making my FC rise

Has been very stable all summer. The last week or so it has been creeping up about a 1/4 to 1/2 ppm per day
A few days ago I started to lower run time. No change so I lowered % from 45 to 35, no help

Any ideas?

Current levels: FC-6, PH 7.6, TA-70, CYA around 50

How has the weather been the last week? Cloudy weather could cause FC to rise.

Another, less likely possibility, someone else is manually adding chlorine.

Another possibility...Has there been a sudden decrease in bathers? It could be a combination of several factors, including those that Jason mentioned.

Yup, it has been cloudy, a fiar amount of rain, temps have moderated a bit as well and less bathers. A good problem eh?

Thanks for the input
