The Hanna Alkalinity checker is an awesome little tool that now will give results in DKH values that are much more common in the aquarium hobby. It will also give you accurate easy to read results with the large LCD display. We like the repeatable results and ability to purchase replacement reagents when needed. The biggest key with Hanna checkers is keeping the vials nice and clean for consistent results.
