Need help w/ parameters...

Didn’t mean it like that. Just saying based on what I’m seeing (I’m by far no expert) that the Hanna is giving a lower number. Just looking back on my log I’ve been having low Alk issues since I started using the Hanna. Levels has steady hover at 5.8-6.1. However, PH has been normal and corals look good. Maybe I’m wrong? Just trying to open a dialog

I know - same here - I'm just saying - there is no way to know whether your hanna is measuring low or your Salifert is measuring high - unless you do a 3rd test and see which 2 agree (hopefully you won't get a third result). So - using what you were saying - what if the 'higher' results you were getting before using the Hanna were actually 'wrong' - do you see what I'm trying to say?
