Hello,
I have a question about the Hanna Alk reagent.
I test Alk once or twice a week so a reagent lasts about 15 to 20 weeks.
I have noticed with the last 3 bottles of reagent that at the last 5ml or so that the readings have drifted down by about 1.5 dkh
A new reagent bottle shows the "correct"reading
any ideas wht this is happening.?
I have been using the hanna alk tester for years now without a problem until now.
