Hi
last night i checked my Ca with Hanna multiparameter tester i used Hanna extra deionized rodi so that i get accurate tesults. I got 360ppm after the test i decided to make second test using Salifert profi test amd i was surprised to get 440ppm !!? What the,,,, ell could we ever get a proper range with hanna ? I mean there is just no way to get a clear accurate result for Ca with hanna !? From now on i will not waste time with hanna Ca test . Anyone have same issue ? Anythoughts?!
