    Fc - 10.5
    TC- .5
    Ph - 7.5
    aly- 120

    The water is clear and nice should I drop my alkalinity or not
    And if so should I use acid

    If the pH is stable at 7.5 or so, I would not screw with the TA at all. If pH raises above 7.8 then I'd use acid to lower both pH and TA and then aerate to bring the pH back up.
