red sea pro magnesium precision
So I'm testing magnesium with a fresh red sea pro test kit...
I've spent the last night testing repeatedly, each time the same. I've been using the SR Aquaristik magnetic stirrer, so it's not a matter of me not stirring enough rinsing with RODI water between each round also tested with a different red sea pro kit, the trace elements so far i've gotten 1200, 1240, 1280, 1320, 1360, 1440, 1400 i'm a quarter through a bottle of the C reagent, and I have no idea where I'm going wrong. this is from two red sea pro test kits, and the lack of precision is insane anyone know what's up?

You are drying the stirrer between tests?
I am using a plastic card to level any spoon of reagent to keep that element very close each time I use it.

I haven't used that kit, but there might be an issue with the speed of the reaction. Do they specify a waiting time between drops for the final titration?

The Salifert always worked for me.
