    First Try, Where to start.

    Ok, I drained the pool last night, probably 60% or so. I had CYA levels over 100, so this seemed like a good place to start while waiting for my TF-100, which came today. The pool was refilled by mid morning, DE added and it had been circulating for 5 hours or so before I tested. I took a water sample to the Pool store and did my own tests, just to see how we matched up. Here are the results:

    TF-100
    FC .5
    CC .5
    TC 1
    PH 7.5-7.8
    TA 60
    CH 320
    CYA 30
    Temp 72

    PoolStore
    FC 0
    PH 7.6
    TA 60
    CH 200
    CYA 30
    Phosphates 1000


    From looking at the Pool Calculator and recomended levels, I should bring my FC up to 5 or 6, so that is about 2 gallons of bleach. I should bring my TA up 80, which would be about 6lbs of baking soda.

    My Questions are:
    1. So should I do one before the other, and if so which one first and how long should I wait before the other?
    2. Should I be concerned with the Phosphates? How should I handle them?
    3. How do I know if my pool water has copper in it?

    Thanks, I can't say enough how much I've enjoyed finding this site.

    You can add chlorine and raise TA in either order with only a few seconds delay in-between.

    Ignore phosphates. They don't make any difference as long as you maintain an appropriate FC level.

    Unless you have some reason to believe that the pool has copper in it, assume that it doesn't.
