"After about the fifth month of use every weekend it start throwing readings completely off. Mostly the calcium first reading I get 472 which is bizarre for me then second reading at 442. I lost all trust into my hanna checkers for these discrepancies. Who knows how long I’ve been getting readings completely off and dosing when my reefs probably didn’t need it. Turned my back against hanna checkers and would love to return all there supplies for a full reimbursement. SALIFERT IS THE NUMBER TRUSTED BRAND FOR PARAMETER TESTING and will always be number 1 for me. Thank you hanna for wasting my time ! Trash"

Hanna is the most accurate and the best quality. I use it several times a day, worth the money. It functions great and is not too difficult to figure out.

I especially love the salinity tester. So quick and easy to use. I love it so much! I wish the Calcium tester didn't have so many steps but otherwise all checkers work out fantastic!

This Hanna kit comes with almost everything for your saltwater aquarium. I invested in this along with the individual checkers and I have to say, they are all amazing! The only thing I hate is the fact you have to spend money on the reagents needed for the checkers, etc. — However, this kit is truly worth the money! :)
