    First time Opening with TFP - Advice on my plan

    Took the cover off the pool today!

    Cloudy, but not green, so pretty happy about that.
    After some vacuuming and having the filter run for about 4 hours I did my tests. (waiting on the FAS DPD add-on kit, so just used the Taylor 2005 so far)

    FC 3
    TC 2
    CC 1
    PH 7
    CYA didn't register (so < 30)
    CH 150
    TA 60

    I took the water to the pool store to confirm - first time using the Taylor kit.
    Their values were

    FC 2.67
    TC 2.98
    CC .31
    PH 7.3
    TA 69
    CYA 5
    CH 189

    My plan is to first get CYA up to 40 - hung a sock in front of the return
    - as this is a "expensive" test to run, since it uses so much of the reagent - when would be a recommend time to test again, now that I've got my sock in there?

    What's next?
    Pool store has my CC < 0.5, so I dont think I need to SLAM, but am open to advice on this as it's my first time with this method.

    after opening, and vacuuming the shallow end.

    Give the CYA a week to dissolve before testing again.

    I recommend adding about 3 ppm of chlorine this evening. Then tomorrow switch to targeting an FC level appropriate for your CYA target level.

    I would bump the PH up to roughly 7.5.

    Otherwise you should be alright for a while.
