Don't know what I'd do without it
By adammahne on December 28, 2018
Love this thing, just picked up the new dKH version. Finally no dealing with color matching.
By statru on July 5, 2017
No more color matching and highly accurate (and priced).

The best device for testing alkalinity. Definitely a must for any reef keeper, I'm using mine every week.
