Is DPD Reagent #1 (R-0001) the same as FAS-DPD Titrating Agent (R-0871)?

I have a Taylor K-2006 complete test kit. I'm in mid-SLAM of pool and just realizing my R-0871 FAS-DPD titrating agent is near depleted. I planned to go to local Taylor rep in town and pick up new bottle but got a funny look. It seems everyone around here talks in terms of K-2005 kit and their chlorine reagent is R-0001. Could/should this be used in place of R-0871? Can it get me by until my 0871 reagent arrives? Help!

No. They are completely different. Why else would Taylor give them different numbers? And people wonder why pool stores get such a bad rap around here......

I am new to all this, and going through R0871 pretty fast. When I reorder, I will be buying 16 ounces from Amazon, at just a little bit more than 2 ounces....

I don't want to break any rules here by posting the link, but a quick search will show you that it's way more economical to buy the larger quantity. And Amazon ships pretty quickly.

Best of luck!
