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.
