    Low CH/TA

    My CH and TA typically run on the low side and my ph rarely swings.

    All last year it ran solid at CH 100 TA 50 ph ran around 7.4 all summer. I used less than a half gallon of acid.

    My CH has dropped and I want to double check to make sure I am still running okay.

    Today's test results:

    CL 8
    CC 0
    CH 75
    TA 50
    CYA 40

    Thanks,
    Chris

    Re: Low CH/TA

    Your numbers are fine Chris, although you didn't list the pH. Chlorine (FC) is a little strong for your CYA, but okay for now. CH is just fine. As long as your pH is between 7.6-7.8 you are in good shape.

    Re: Low CH/TA

    Your TA is fine if your pH is stable.

    Being that you have a vinyl liner, you do not need CH in your water. Although if it gets too low and you start seeing any foaming, then bumping the CH up a bit would likely help stop the foaming.

    You FC is a little on the high side for your CYA, but it is not really a problem.

    Thanks for the reassurance. I know my CL is a little high. I was talking and doing my CL test at the same time last night. I guess I can't count drops and talk at the same time LOL.
