Reagent issue with Hanna Nitrate HR?

[saltyhog]

I just opened a new box and some of the reagent packages look vastly different than they have in the past. They also give unexpected readings.

These are two packs from the same box and lot #

It doesn't show up well in the picture but the packet on the right is a pinkish/rose color while the one on the left is the normal light gray that I usually see. Performed a test with both packets. The one on the left read 8.8 which is very much in line with recent readings for my tank. The one on the right read 0.8! This is third packet that looks like this so far in the newly opened box.

Lot # is H036 with an expiration date of 10/2027. Anyone else had similar issues?

I just had same issue with lot H035 of Marine Nitrate HR reagents:
About half of the 10 or so I've used seemed damp/clumpy inside and tested at 0.1 ppm (WAY INACCURATE / LOW).
About half tried were fine and would test at regular 10-ish ppm on same water sample.

I reported to Hanna on their website support form and they are supposedly sending me a new reagent pack for free. (Don't have it yet but their response was just yesterday)

I've had a few the same way recently. Was testing nitrates at about 15 and then a random 2 on an extra clumpy package of reagent. I didn't think much of it then 3 days later tested back at about 16. I should have re-tested when I got 2. Phosphate steady at .05.

I got a couple of bad one's as well in a kit I recently bought.
I bought a 25 pack replacement regent set from premium aquatics and they're all good.
When I saw a 3 that's when I knew.

I had a similar issue, but not recently. Must be a bad batch.

I just noticed a similar thread for lot H034 a couple/few months ago.
In that thread, Hanna suggested emailing:

Support form on Hanna website seems to have worked for me also, in this case.

Here's the other thread with Hanna response if of any interest:

I was just about to post this because our packets are inconsistent and getting crazy low readings!
