Not opposite, that's the same that is happening to us. Seems that as the reagent is used the readings go down. I just got a new reagent in 2 days ago so I'll give it s try later to see how my old and new bottle compare this time. Only thing I've been doing different since the last new bottle is giving a light shake before each use.

I've got the calibration solution for the ALK checker. Remind me to bring it to the next meeting you're going to attend and we will see if your checker is within the limits.

I shake the bottle each time. My response from Hanna is not very good. They know they have problem, but won't tell me what is going on and won't respond anymore. The only thing they asked me was what color the reagent was. Won't tell me what the color difference means. Might go back to Red Sea and sell this thing.

Those 2 bottles are less then a month old and purchased through BRS at the same time. I thought maybe the previous ones I purchased via Amazon may have been old, but the expiration dates were the same.

Ok hold on. I have tried to explain the issues many times over.
These are as accurate as you make it. So I have put together a response to this thread.
1 bottle is 30 days old and the second I just opened for these images.
So lets start!
Here is the 30 day old reagent
Vial must be clean of ALL AIR bubbles, smudges and fingerprints.
Next the measurement of the reagent has to be exact!
Now when you put this in the vial again no smudges, bubbles or prints
Here is the result
Now on to the new reagent
Again no smudges, air bubbles or prints
Now the reagent exactly measured
Now again introduce the reagent with an absolutely smudge free vial no air bubbles.
Here is the result
I can reproduce this all day long..
My tank sits at 160
Now it was my fault on the first test it dropped from my picture platform.
So before there is any bad naming companies make sure you are doing these tests like your in a lab.
Thank you for looking

This is how I do it. Your assumption that we are doing something wrong is inaccurate. The only reason I brought this up as 8 months of things being spot on with the Hanna Checker, I have noticed this anomaly in reagents just in the past month or so.

only thing I can see is that I am using the applicator on the end of my syringe and you are not.
Not to be rude, but when you make comments like "Just giving the facts", it assumes we are not doing is correctly. The FACT is I do this 3 times a week and each time with a new bottle it comes out spot on, then when the reagent bottle gets low it gets off.

Hey now I am not coming down on you at all.
Just showing others how to properly use the Hanna checkers.
I test my water every day. What else do I have to do lol retired
I used to get bad reagents form the red sea ALK test. I can see it right when I unpack it.
Its disturbing for sure!
I get the reagents 4 at a time of the Hanna ALK and so far never an issue since they came out.
If you believe you have a bad reagent then contact whom you bought it from for a replacement

I'm glad you showed us how to used the Hanna kit properly. That should solve all of out problems. Oh wait, it didn't. the reason why it didn't is because there is clearly an issue with the reagent as it nears the end of the bottle. Perhaps it settles a bit and needs to be shaken more then normal, perhaps it something else. Either way this is an issue that has occurred with different people at different times and with different reagent Lot#'s. If this was 1 person sure I'll give the benefit of the doubt, but at least 3 here has had this issue and on the other site there are several more with the exact same problem. Heck, apparently even Hanna has acknowledged the issue.
That said, I invite you to read this whole thread again and ask yourself at what point did your teaching us seem warranted.

People who live up north are a little testy.
