This technique is making the news over at R2R as Randy Holmes Farley did a writeup. Just think, we had it here first, thanks reefnjunkie!
My 0.1N acid came today. Like the kid in Christmas Story I rushed up to unwrap it and to the titration test.
So I heard this rumor, a rumor that Hanna measures 18% low on alkalinity. So I have been subtracting 18% from it's ready to get to my target (7-8 dkh).
Results:
9.24 Hanna (with the 18% adjustment I was thinking, around 7.6, perfect!)
10.64 Titration
Uh oh.. Crud! Hanna is less than actual, not 18% more?? I have been higher than I thought the whole time?? Ugh.
Time to bust out the SF test and have yet a third number.
So 10.64, too high? Higher than I was shooting for...
