Hanna dKH, bad batch
I have been using the Hanna checker for ALK and have been happy with the consistency. Whenever I open a new bottle I always run side by side tests and results are usually close enough for no real concern. (I am OCD about dKH). The last time I did that the old had been returning 7.8 dKH and the new 6.6.
I also rechecked wit ELOS (7.5) and Salifert (7.6) I have 3 bottles of batch 8549 and checke them all. they all came back 6.6. Looks like Hanna may have a bad batch?

I do the same as you. I use the older ppm version. the most I've seen reagent off is 2 ppm from one batch to the next and most of the time it's exactly the same....I even used the bad batches from a few years ago and they were ok too.....I'd definitely give them a call and tell them...

I would have to agree that you got a bad batch. Maybe they will accept a return.

BRS (Bulk Reef Supply, www.bulkreefsupply.com), stepped up and is sending replacements. Hopefully not from the same batch.
