    I want to go back to Blue from Green

    Hi......I have been following your methods since last year. I went on vacation for 1-1/2 weeks, instructed my son to read and apply chemicals as needed; however, when I returned, my pool is green.....here are my readings. Please let me know what I need to do to get back to blue and accurate readings. Thanks.

    TC=8
    pH=7.8
    TA=90
    CH=140
    CYA=20

    Ditto....shock, brush, test, repeat until water is sparkly and test numbers are in range..... run that filter 24/7!!! What about your CC's? Read in Pool School your recommended ranges...you're a tad low on the CH number and your CYA could be bumped a bit. I'm guessing your son didn't do as he was asked....
