I went back to my old posts on here and looks like I got it back in September literally around this time haha. Doing the same exact thing I was doing last year. Checking against the stupid Hanna reagents!! Which are once again wrong. I just got this reagent as a warranty replacement from Hanna too. The paperwork says “bad lot” in the description.I'd use it in a pinch. Get new if you can. I love using the Salifert Alk test. Its so fast , easy, and accurate. Gets way more milage than my Hannah Alk checker.
If it makes you feel any better mine expired on April 2022. Its almost gone tho. lol
Yea it is. It’s the Hanna reagents I’m checking against that are absolutely terrible.As long as it’s returning “normal” expected test results, I’d use that.
