Hey Everyone, Hanna is recalling many of the Reagents for the alkalinity tester. I stumbled across this recall today and am so glad I did. Hopefully this keeps others from incorrectly dosing their tanks!!!!! In order to see if your Hanna Alkalinity Reagent is useless, go to this site and put in the Lot # of your solution (written on the package and bottle)
