    I love my Hanna Checker

  • A Must Have By Charles on 2/28/2015

    These save time and really are a must have, accuracy is right on point!
  • Extremely Easy And Accurate By Ceasar 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 emak on 1/1/2015

    Absolutely love these, I dont know what took me so long to invest in these.
  • Good product horrible containers. By Samsffr 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!
  • hi758 calcium reagents refills By chuck on 12/14/2014

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