  • The best calcium assay we've found By on 11/25/2015

    We've been using the Hanna Checker for calcium for over 18 months. The method is simple and easy to follow. When we run replicates, we find that we get repeatable and reproducible results that are more discernible compared to other methods available in the hobby.
  • Accurate & easy to use By on 11/25/2015

    I've found if something is easy to use I use it more. Hanna checkers are simple to use and accurate. Since using Hanna checkers I test more giving me better results.

    Everyone can agree that testing can be a pita, but with hanna it is a breeze. Just collect some water from your aquarium and add some reagent, and place into the tester. Eliminates the headache of wondering if you matched it to the right color on the chart or not.
