    My results after draining of water - thoughts?

    I drained a little more than 1/2 my pool, and refilled with tap water. I intend to go with liquid chlorine now, instead of Trichlor / Cal-hypo the pool guys were using.

    Just tested results:
    25000 gallon inground, vinyl-lined pool
    82 degrees (water)
    Direct sun from 8am to 4pm daily.

    CYa: 50
    TA: 90
    pH: 7.2 (LOW)
    FC: 6.5
    CC: 0
    TC: 6.5
    CH: 240

    All good except pH. I added roughly 32oz by vol of soda ash. (I say roughly because I didn't have an exact measuring tool).

    Thoughts?

    Looks swimmable.

    I wouldn't have added soda ash - TA is high enough that some aeration would fix pH.

    Do you think I'll now end up with too HIGH of a pH?

    Probably not but if you do it will be easy to fix. Aeration would just be a means to raise the pH without adding chemicals.
