Good Morning,
Joined the group in June and you guys helped me maintain a Trouble Free Pool all summer long. Lately, however, my chlorine levels have risen without adding chlorine to the point of 10.8 this morning. I had seen it in the 7 and 9 range in the last couple of weeks. The 10.8 this morning was after draining about 4 inches of water yesterday from the Hurricane Matthew rains. Below I have listed my other readings. Is this normal (obviously temperatures have been dropping)?
Chlorine 10.8
pH 8
alkalinity 60
calcium hardness 350
CYA 90
Salt Generator set @ 50% reads 3,100 ppm (this usually reads 3,300-3,500)
For what it's worth, I swam last week at the 9 chlorine range and eyes were fine. Thanks for the help.
