Thanks Dave

I just got the FAS--DPD kit from Taylor 2 weeks ago --- and my R-0003 from the standard kit is fresh for 2006. I've used both methods -- same results--no change in color (still clear with FAS-DPPD method) after adding that reagent!!

I wish Taylor would date their Reagents --- there doesn't seem to be any rhyme or reason to the batch number.

My results this morning are the same except FC dropped to 6.5 and the pH 7.5
