RECALL: Check Your Hanna ALK Reagent NOW!!

[Myka]

Thank you for sharing!

I entered my lot#5489 and it says mine is bad too even though it reads the same as my Salifert test kit. Weird.

From my one day research it shows as all reagents from Q2 2015 and up to today(unless new stock) is bad, so best to check the reagent and check against a different product like RedSea or Salifert.

I checked against a friends Hanna a while ago and results were similar... little did we know both of our reagents were off...

That probably means the whole last bottle I had was "bad". I always check alkalinity against both Hanna and Salifert since it's so important, and I've always had very similar results, including this "bad" batch of reagent.

I'm going to move this to the Reef forum just so that more people see it.
