    test sequence

    Hi
    I test twice weekly in this sequence is it OK

    1 FC then adjust
    2 TA then adjust
    3 pH then adjust

    The water hardness is >500

    I thought I saw the light at the end of the tunnel but it was just some PERSON with a torch walking toward me.
    I started out in life with nothing and I still have most of it left.

    Re: test sequence

    What kind of test kit are you using? And how long have you been doing it that way? Your order is fine, although you probably want to test more often for pH and FC, either daily or every other day. How does your water look?

    ^^^what he said

    also, here's a link to suggested basic pool care schedule in Pool School:

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Re: test sequence

    Just be aware that high FC can throw off the pH test, as to sequence I would test most often the thing that tends to drift most on your pool, experience will tell you what that is, but it will most likely be FC or pH depending on your pool, if you have an SWG, etc. For example on my pool the pH is usually very stable so I only test it once ever couple of weeks unless I have recently been using other chemicals that have acidic side effects like dichlor, trichlor or CYA, by contrast someone that buys acid (or Borax) for pH adjustment on a regular basis instead of my once or twice per year might want to test more often.

    Re: test sequence

    Hi
    I have a bio-guard multi test 1200v and a desperate tester for water hardness, and have been testing in this order for 6 months I was told that the TA had to be adjusted first because this changes the pH setting.
    The water is clear and I test twice a week for FC Ta and pH.

    Adjusting TA does change the PH just a little. However, unless your TA is way out of range, it won't change the PH by enough to matter.

    And its not a desperate tester for hardness its a separate.
