    First post, first results with TF-100

    FC 1.5
    CC .5
    PH 7.5
    TA 120
    CH 200
    CYA >100 (150 by pool store)

    Now, the background.. My wife and I bought this house late last October.. I have never owned a pool before.. I bought a book, did some research, and stumbled on this site. The initial test from poolstore was bad, the pool looked great but the PH was around 6, TA was way low, and CYA was high (almost 200). Since it was inground vinyl I didnt want to drain it, and being near winter I worked on getting TA back, and then straightening out the PH.. then put the cover on. Opened it up this spring, using BBB only to revive it,.. and after working a bit, water is clear, here are current numbers(I did this before adding the bleach today so not to skew the numbers):

    Current plan:

    - Get Liquidator.. use bleach only
    - "over backwash" and 'top off' to work on moving CYA down ( I might have to work on one of the returns soon which would make me drain a bit.. so I am waiting to get the right parts for that so I wont have to do it twice)
    - monitor regularly


    Thoughts? I have learned a lot just reading posts here.. wanted to see if I am on the right course.

    You really want to get your CYA down, but you know that already.

    You need to adjust your FC level based on the current CYA level. With CYA of 150 you need to maintain a FC level of at least 12, and preferably more like 15.

    Your other numbers are good. You can let TA go down to the 70 to 90 range, but there is no reason to put effort into making that happen right away.
