    ph 7.4
    cya 40ppm
    TA 450ppm
    FC 5
    TC 5
    TC 0

    You should wipe the tip of the titration reagent bottle with a damp tissue and do the TA test again, wiping the tip every five to ten drops. Sometimes the dropper tip can build up a static charge that causes the drops to be smaller than they should be, which can cause very high, incorrect, readings.

    A TA of 450 is very high and could lead to calcium scaling. Hopefully it is just a testing error.

    So, with that resolved, it sure looks like your water tests to be perfect.

    Water test -- check
    Water clarity -- check
    Sparklyness -- check (?)

    That looks like a TroubleFree Pool!
