Both are newly opened. Being I've read if this issue here and elsewhere I emailed Hanna support and they are sending me two replacement bottles. I plan to check these against the news ones in my testing routine. I try to test every other day.

I thought I had reported this in this thread but I came across another bad bottle. I quit using it and will be sending it back to Hanna. The bottle I'm currently using has been dead on but I'm still not at the halfway point. Been testing with Salifert as a backup as well so far so good, but I'm not deep enough into the bottle to where the issue usually starts. Lot was 5444 if I remember right. It wasn't off by much , but it did start to trend towards lower readings midway through the bottle. Was off 10-12ppm. I still have the bottle, maybe I'll use it to see if sitting for a few weeks in my cupboard affected it any.
Yeah, I've given up too after yet again another bottle drifting low, and this is with double testing with salifert. Sucks because I love the convenience and ease of use of the checker.....I'be had two bottles that produced low results. Burnt a lot of corals when I raised my alk too high based on false readings. I stopped using my Hanna checker over the summer and switched back to Salifert.
Hanna is aware of this problem-please contact me at [email protected] and I will give you information for an exchangeLot 5441 exp 9/16 appears to be a bad batch.

And if some didnt get effected? Thank youThank you. I am going to share your comment with others!!
