    Partial drain needed

    Hello,

    I just wanted to double-check on doing a partial drain. According to the Pool Calculator I will need a 40% drain in order to follow the recommended levels for SWG by TFP.

    It is correct to do a partial drain right?

    My numbers:

    FC - 12
    CC - 0
    pH - 7.5
    TA - 70
    CH - 400
    CYA - 110
    Salt - 6000 (target will be 3600)

    Thanks

    From what I calculate, that would get your CYA to around 65 (assuming it is 110) and your salt to 3600, so I say go for it.

    I have the Taylor Kit K-2006 so this is what I used to get my results. Sounds good and thank you for the quick reply, I do appreciate it.
