I'm opening my pool for the season and for the past 2 days I have had no chlorine loss (maybe 1 ppm) overnight, but my pool is still quite green (can't see the bottom of the shallow end). I would think that I'd be loosing chlorine quite quickly - and I was for the first 2 or 3 days of the opening process.
CYA was 50 yesterday but there is still about a half pound of CYA in the sock (getting ready for salt system)
Temp - don't know, thermometer broke and don't want to put the new one in until the water's cleared up, but it's freakin' cold.
I backwash about once a day (or when PSI raises, whichever comes first).
What am I missing??
