Yes, you can use a syringe to measure 10 ml for the greatest accuracy. How far above the line is it?

mine is quite a bit over the line.

Anyone else experiencing this?

yes but the capillary effect makes makes it look higher then it is to.

I understand that, but this is wayyyy beyond any capillary effect.

I have used multiple syringes from different test kits. I am currently using the 5ml one that is included with the Salifert Alk kit.

While we are at it, how about an answer to the question about using the tip for the syringe with the reagent. I was wondering this myself, but your previous responses were a little less than helpful. You have pointed people to another thread that discusses the issue. In that thread there were many people who claimed that they were told by your techs that the tip MUST be used or too much reagent would be used. In that same thread, other people claimed the tip was not needed. Which is it? I am interested in what Hanna's position is on this matter and not my fellow reefers.

If you are measuring 10 mL of sample with a reputable syringe and you are confident that it is correct, go with that.

Our position is that the tips must be used for accuracy and to prevent contamination.

We listened to the feedback that the tips in the kits were unsatisfactory (i.e. they got smooshed in shipping), and are working on sourcing a new tip.

You can use it without the attachment, but we can send you a new syringe if you'd like.

Thanks, by following your previous advice my tests have been inaccurate and I have likely contaminated the reagent, although I am not sure how not using the tip would lead to contamination.
