I guess the alkalinity reagent decays once open.
I confirmed the report the older the alkalinity reagent the higher the reading.
I bought a new reagent and tested it against the older reagent.
Older reagent 8.8, New reagent 7.9.
This is the second time I notice the discrepancy.
Maybe I’ll try refrigerating this new bottle of reagent.
Does anybody know how to keep the reagent stable?
