So I’ve measured my KH with two different API KH tests and they were quite different from each other. I would’ve accepted one or two DKH difference but it was a difference of 6… one measured 10 and the other measured 16. Anybody else have experience with this? I know I’ve heard people say API aren’t really that great, but could it be that bad?
side note- I’ve heard good things about salifert tests, can anyone confirm?
Thank you!
