Does anyone on here use a hanna checker? I have one idk why for the past few days it been reading my calcium is at 596 -443ppm. Anyone else have this problem?
Can you tell me why this is a problem? It sounds more like the test not being done correctly.
How far in between tests? If it is in the same day, it can only be an issue with the reagent or it is user error at some point. I really liked my hanna checkers, but it eventually turned into being too much work to do as often as I was.
