    pH color too intense

    so with 5 drops R0004 color is too intense to read
    with 4 drops still too intense
    with 3 drops reads well

    why is recommended 5 drops too intense?
    is 3 drops Ok?

    Re: pH color too intense

    What is your pH?
    Which kit are you using?
    Are you sure its R0004 reagent you are using?
    How old is the reagent?

    Re: pH color too intense

    Sounds like you may be using the wrong reagent for your test tube ... there are two that are different "strengths" R-0004 and R-0014

    Did you recently buy a reagent refill? Which kit's comparator are you using?

    The number of drops does not really matter if this is just a case of the wrong reagent (4 vs 14).

    There are other threads about this if you search:

    Re: pH color too intense

    as always thank you

    checked out the threads but all seem to discuss 0014 vs 0004
    but this is clearly R-0004 and K-2005
    but Bama asked about age of reagent, ie quality so...

    I have been refilling the little R-0004 from a big one so can put it away in the case
    ?contaminated

    I have another bottle of R-0004 and tried it, works fine
    Then I emptied the little bottle, rinsed it out, refilled it and it now works fine

    I guess I contaminated the little bottle somehow

    Re: pH color too intense

    That's good detective work you did finding that out.

    I wonder what the contaminate was?

    Re: pH color too intense

    I think will never know but a rule(s)...
    if test does not work, try a different bottle
    and maybe
    do not refill little bottles
    or if refilling
    rinse out and start fresh
    or something
    or not

    Re: pH color too intense

    I have both the Taylor K-2006 and the TFTestkits TF-100. The R-0004 pH test with the K-2006 is also dark for my comparator and I use 3 or 4 drops instead of 5 so this does happen and it's been that way for multiple bottles so I don't think it's contamination, at least in my case. It could be that the comparator has faded as it is older -- I'd have to get a new one to be sure. Since it's the hue that is important in comparison, using fewer drops is OK unless the chlorine level is higher in which case there might not be enough chlorine neutralizer so you may get a falsely high pH reading (though with CYA in the water it takes some time for the chlorine to affect the pH dye).

    Re: pH color too intense

    emailed Taylor
    they said both of my bottles as identified by lot # should work, not expired
    they also said if 5 drops does not work something is wrong; use another bottle
    so it goes...

    Re: pH color too intense

    well
    now 9 months later same problem, pH color too intense to read
    will need to try new bottle and new comparator

    Re: pH color too intense

    Did you ever try using fewer drops?

    I did and that makes it better
    but Taylor person said "if 5 does not work, something is wrong; you should use 5"
    and chem geek said fewer drops could mean less neutralizer and falsely high pH
    so may be time for new stuff, may be time for the tfp stuff
    in fact
    I will go read about it now

    Re: pH color too intense

    so ordered the TF100 large
    will be sad if it does the same thing

    Re: pH color too intense

    I almost always need to use 3 drops and never more than 4. Perhaps my comparator is faded, but I wouldn't worry that much about using only 3 or 4 instead of 5.

    Hi & thank you

    based upon using 3 and 4 drops, I think you are correct

    but it bugs me
    so I got a new bottle

    now all is fine, funky colors gone
