    PH Test Color

    Hi to all;

    When doing a PH test the color, after adding 5 drops of R-0014, is a very dark orange not matching any of the colors on the vial. I noticed this at the end of last season too.

    Anyone else experienced this issue?

    Thanks,

    Gary R.

    That means your pH is very low. Not good.

    Re: PH Test Color

    Thanks for the reply!

    Probably should have added:

    FC=6
    TA=60
    CYA=15-20
    CC=.5

    Just opened pool yesterday and using pucks to bring CYA level up.

    Will add some baking soda to get TA & PH up

    Thank you,

    Re: PH Test Color

    The pucks are pushing your pH down lower. I would suggest Bleach and stop using them for the time being.

    You may not get all the pH rise you need from the Baking Soda. I would suggest Borax or Washing Soda (Soda Ash) to raise the pH.

    Thanks again for the reply!

    Just put the pucks in yesterday and did use soda ash rather than baking soda. Will test again in a couple hours and see where we are.

    Any chance the reagent is too old? They are from last year.

    Regards,

    If they were stored inside, or where they didn't get really hot or freeze they are fine. Good move on the Soda. Let us know how it is later.

    Re: PH Test Color

    Things look better:

    TA=80
    PH=7.5?
    Part of the problem may have been that the color chart had faded a bit so used a new vial. Probably hard to tell from this pic but the color is definitely not yellow or orange now. Looks like it's right at 7.5 or 7.6 but the color is darker than the chart.

    Thanks again for your help!!!

    I took the liberty of posting the IMG Link below. If you will click, copy, paste the IMG link, the photo will show up in the body of your post.

    It looks like the sample is not mixed, or there is a lighting fade out at the top of the vial. Can you confirm that? It's either that, or it's too shaded in this photo. Shaded out on the bottom of the test vial in this picture. My best guess at this pic is about 7.6-7.7

    I think you need a better white background ... or use the clear blue sky.

    Re: PH Test Color

    Just wanted to follow up on this thread:

    Purchased a new bottle of r-0014 and it reads just fine. Seems like the older reagents had become concentrated and made the water a very dark orange.

    Thanks,

    Good! That one degrades, and it's cheap to replace. Compared to many reagents phenol red has a short life. Being as important as it is, there is no reason to risk it.
