I have run the experiment twice and the delta is consistent.
Red Sea titration kit (very old) is a completely different number like 3.8?
I am just going to believe the new value as it is the number I want.
Is that not the basis of science? Cherry picking the data to agree with your confirmation bias.
I thought someone sold dKH check packets? Don't get me started about my Hanna Salinity checker. Complete trust.
ICP test?
Ugh, as the days go by, I will just accept the results until I order more but that might be a ...
