A lot of people were getting low salt indicator the way you were doing it. As a matter of fact that's what I got when I didn't read the manual at first since it was kind of straight forward to do it that way.
But yeah man I don't mind the taste either but my girl kept adding some crappy vitamin c pockets so I found a bag of TANG (didnt know they make it in grape, lime, orange and pinaple).
Still the syringe is not much as a salt saver but keep my stuff dry thingy.
