    Pools been open for about a month chlorine loss ok?


    Pool open for about a month, Temp 81 (heater turned on today). I had a ton of issues last year and want to make sure I'm not heading down that road again this year.

    FC - 5 - was 10 this morning. Scrubbed walls, and the pool was open most of the day (very sunny).
    SWG was set on 4/5
    CYA - 60-70
    CC - 0
    PH 7.4
    Total Alk - 180 (high side)

    I turned the SWG up to highest level. Anything here you think is of concern? Water clarity is perfect. I saw a significant drop today. Not sure if that was a combo of turning on heater, heaviest load of year. Im more interested in the chlorine loss and hoping it was the first use of the year and it will recapture. Should I add liquid show or wait the night?

    If you had several people swimming, then that sounds normal enough. If no one was swimming then something is going wrong.
