Review on Hanna Instruments HI 755-26 Alkalinity Reagent Kit, ideal for Alkalinity Checker HC with 25 Tests by Tamara Allen

I love all of the Hanna tools I have and are an inexpensive way to constantly test my aquarium parameters. Check the recall on the kit you are receiving, my last batch was recalled so am awaiting a new batch direct from Hanna. So you might not want to wait until you run out of solution before placing an order, Hanna will ship a new batch in 2-4 weeks.
