FYII feel comfortable raising it up to 0.5 dKH in a day. I’m not sure if there is a commonly accepted rate.
I have had my Hanna Alk reagent go bad, and read persistently low. When I got a new bottle my alkalinity was 3 dKH higher than I thought. Consider a backup test method or new reagent bottle to be sure

Yes, thanks Lasse. I have been storing it in the refrigerator for a while now.FYI

Important findings according how to store open bottles of the reagent for Hanna Marine alkalinity checkers
There is a way to hinder the Hanna alk to show lesser and lesser dKH (or ppm for that matter) with age of open reagent bottle. I had the same story as many have reported here - my reading decrease from a new open bottle with time. Double check with another method show that there was not a real...www.reef2reef.com
