I got my annual refill from TF Test Kits, and took my first reading today. My FC reading came in at 12.5, which I recognized as out of the ordinary. I retested with last year's reagents, and got 7.5 (as expected). I had not added any chlorine or run my SWG since yesterday.

Repeated with both. Also used last year's 871 reagent with the new year's powder. Same result. I keep my reagents in a dark cabinet, inside, year-round.

Has anyone had a similar experience with the new year's reagents. The 871 reagent bottle looks different, for sure. Maybe it's susceptible to the static buildup?

Edit: just checked pH with R-0014 and got a valid reading of 7.2 (low bc of CYA addition).

Ok, sir. I'm a fool. That seems to have resolved it. Getting FC=6 with the new guy after wiping, and the drops are noticably fatter now. Many thanks.
