I need to order the FAS-DPD reagents. I have a decent quantity left over from last year's test kit I got from Ben, and they're still working fine, but since I heavily depend on this test to get accurate readings (the drop kit has never worked well for me and it still doesn't), I will need more as the summer moves forward. It doesn't make sense for me to buy a whole new test kit from Leslie's or some such store because I use the drop kit for pH of course, and I still have enough CYA solution to test the few times I need to this pool season, and I don't need to test for anything else. In last year's kit, they're called FAS-DPD #1, #2 and #3.

I did find on one pool's website:

Taylor R-0870 FAS DPD Powder for K-2006 and Taylor R-0871 FAS DPD Titrating Reagent for K-2006, and I do now recall from Ben's 2005 test kit that these are the right numbers, but what would be the third one, the one that measures for combined chlorine? If it's R-0872 (which would be logical), the particular website I've got pulled up doesn't have that one. Perhaps someone can steer me to a website that has all three, and also confirm that the equivalent to the FAS-DPD #3 is indeed R-0872?

I appreciate your help -
