Had similar experience of Hanna Alkalinity getting higher and higher. Returned it to BRS.
As far as Salifert....
I had 3 kits for Alkalinity; Salifert, Red Sea and Lamotte. Red Sea and Lamotte results would be virtually identical and Salifert was consistently 1.0 DKH higher.
Figured my Salifert kit was reading too high, until I performed an acid titration test and found the alkalinity as measured by this test matched my Salifert result.
Salifert, all the way.
If you are into testing Potassium, I can also recommend Salifert's test.totally agree . Salifert all the way . I was use Red Sea test kit . I have to clean My wave pump every week or two weeks . Cause calcium build up inside the impeller . Thought it was normal . When I switch to Salifert I find out my calcium close to 500 , kh 9.2 and mag 1500 . Red Sea test the calcium only 430 kh 8 and mag 1360 .
I was dosing 360ml cal and 250ml alk daily in 75gal tank when I use Red Sea test . Now only 193ml cal and 150ml alkIf you are into testing Potassium, I can also recommend Salifert's test.
