What reagent with this comparator for chlorine?

I have a comparator that's about 4" x 4", in the pinks for pH and in the yellows for CL/Br. The Cl goes up to 5 on it. Which Taylor reagent do I need to test for Cl?

I normally use the DPD-FAS process but my FC stays pretty much the same (3 - 5 ppm) and I could save on powder if I just went with the drop testing. Unfortunately, I cannot remember which drops that would be :(

Anna, what water sample size does the chlorine test use on that comparator? How about for the pH test?

I really can't answer that, WM. The tube gets filled to the line, the water doesn't get measured by volume.

After doing a little online research I'm pretty sure what I have is the Leslie's Deluxe OTO kit which takes 5 drops of R-0600 for the chlorine and 5 drops of R-0014 for the pH.

If it is the Leslie's Deluxe OTO kit, it is actually the Taylor K-1003 which is rebranded for Leslies. I have the exact same kit. Here is the link for the kit at Taylor: http://www.taylortechnologies.com/pr...D=1&KitID=2452

Does the comparator have two little square tubes like this? Then - Yep, R-0600 OTO and R-0014 pH.

Yes and yes :)

Thanks!!
