    How much pool water/R-0013 for the CYA test

    I have the test bottle from the TF100 kit that says fill pool water to the bottom of the label and R-0013 to the top....does anyone know what the actual volume should be?

    You can always fill with pool water to the bottom of the label and then pour that into one of the graduated testing cylinders to get an approximation.

    I remember seeing something about 7ml, but could be confusing that with something else.

    I believe you want a 1:1 ratio of pool water to R-0013 reagent. Specific volume doesn't matter provided it's enough for the test and you're not wasting reagent by using too much.

    FWIW my Taylor CYA mixing bottle is labeled at 7ml & 14ml, a 1:1 ratio (or 50/50 mix) as posted.

    I knew I remembered 7ml from somewhere. So 7ml from the CYA mixing bottle in the Taylor manufactured kits. I think the TF100 CYA mixing bottle is slightly larger.

    The exact 1:1 ratio is definitely the important part.

    Thanks! It's easy to overshoot, so I think I'm gonig to start using a syringe to measure it out. I have a 5ml syringe, so it helps to know the 1:1 rule to make it easier
