  • HI758-25 calcium reagents By on 1/27/2016

    I always have used this product for my Hanna Checker. I have not had any problem with them.
  • 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.

    Easy to use
  • A Must Have By on 2/28/2015

    These save time and really are a must have, accuracy is right on point!
  • Extremely Easy And Accurate By on 2/4/2015

    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.
  • love it By on 1/1/2015

    Absolutely love these, I dont know what took me so long to invest in these.
  • Good product horrible containers. By on 12/26/2014

    I love my checkers, however the regents are stored in containers that are in a word "cheap". I have not been able to put the lids on tight enough to not have some leakage. This makes the whole process a great big mess!

    I like the part of being easy to use, just open the bag and pour the powder into the test tube.
