"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"
