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).

I love it. Easy and fast

By dtum on January 15, 2017

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