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

I really like all the Hanna tools I have and it's an inexpensive way to test my aquarium parameters. Check the recall of the kit you are receiving, my last shipment was recalled so I am awaiting a new shipment 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.
