I bought a Hanna Calc checker today and after using the Redsea test since I started and I believe I was doing it right.
My tests have been consistently 420ish since adding a doser.
Today my first Hanna checker test reports 492?
Is there such a discrepancy or did I do something wrong.
I'll not be dosing Calc for a few days.
But this leaves me wondering how accurate my ALK is also with the Redsea test. Which has been 8.5ish for the last month plus.
I'm thinking I'll have a very out of balance system
